Team 7-Eleven, by Drake & Ochowicz (Book Review)

Team 7-Eleven:  How an Unsung Band of American Cyclists Took on the World - and Won is a new book about the 7-Eleven sponsored cycling race team that was active in the 1980s. The blurb description of the books is as follows:
Founded in 1981 by Jim Ochowicz and Olympic medalist Eric Heiden and sponsored by the 7-Eleven chain of convenience stores, the team rounded up the best amateur cyclists in North America and formed them into a cohesive, European-style cycling team. As amateurs, they dominated the American race scene and won seven medals at the 1984 Olympic Games in Los Angeles. As professionals, beginning in 1985, the team went to Europe and soon received invitations to the Tour of Italy and then the Tour de France, putting Americans on the podium in landmark victories that would change the face of American cycling forever.

Prepared with the enthusiastic cooperation of the team members and co-authored by the team’s founder, Jim Ochowicz, 7-Eleven is not only the most important missing piece in the story of American cycling, but the book that American cyclists have been waiting for ever since the 7-Eleven cowboys snagged that first yellow jersey.
The two authors are respectively a journalist who wrote about Team 7-Eleven (way back then) and Ochowicz, the team founder and manager (among other roles).

I am not an expert on pro cycle racing history, so I will confine my comments to fairly obvious stuff.

The book takes the obvious (and sensible) approach of presenting the story chronologically. The beginning focuses on Ochowicz and Eric Heiden - in the early years of establishing the team. Heiden's role was probably more important than Ochowicz since he was so supportive of the team and was a publicity and sponsorship magnet. The critical piece to launching the team was securing sponsorship from the Southland Corporation, which is described in some detail. (It was connected with Southland sponsoring building of an Olympic velodrome for the 1984 Olympics.) Finally in chapter 5 (of twenty) Ochowicz starts hiring and building the first U.S. 7-Eleven amateur team. The next several chapters describe the highlights of the amateur team's racing before the professional team was established, and the most prominent riders, such as Heiden and Davis Phinney. Chapter 12 segues to the building of the professional team that would compete in Europe starting in 1985 - it is the activities of this "senior" men's professional team, primarily when in Europe, that occupy the remainder of the book. Most of the narrative describes key team developments and critical race successes (and failures). The most well known race successes are covered in some detail, such as Andy Hampsten's Giro stage victory in the snow storm.

The two authors clearly know the subject extremely well and had the cooperation of most if not all of the important team members. Since this was Ochowicz's team, it is probably not surprising that certain more unpleasant subjects are not really covered - in reading this I was reminded of military regimental histories prepared by unit historians. Generally everything covered is given a positive spin - not to say that failures or bad days aren't covered, but . . . One technique is to have negative commentary attributed to other parties - it isn't the authors saying that in their early European racing the 7-Eleven riders were crash happy cowboys; no, that was what the other riders were saying about them. And not to worry; after a few years the 7-Eleven riders matured. Some controversial subjects are simply left out, most notably the almost complete absence of discussion of use of drugs in pro cycle racing.

Whether because of the "authorized history" approach or for other reasons, the description of events is fairly flat; the examples of "wildness" are not very wild, and so on. Bob Roll, for example, is described as "eccentric" and the "team clown" but the included example of his idea of humor rather tame, particularly since one can read far more outlandish stuff about him elsewhere.

Who is this book written for? I'm not a big pro bike racing fan, but I know enough to understand basic tactics (about as much as I know about American pro football, I suppose) and it seems the authors are assuming at least that level of knowledge. For example, at one point a 7-Eleven rider manages to win multiple jerseys in the Tour de France on one day, including a "combination jersey" for best standing in all categories (different than GC) - since this category no longer exists, this is explained, but the subtleties of the other categories are assumed to be clear to the reader.

The book includes a fair number of both color and black and white photographs, chapter notes, a good index, a the senior men and women's team rosters for the years the team was active (otherwise there is little said in this book about the women riders), and a "where are they now" epilogue updating the lives of the main (men) riders.

In some descriptions of the book, it is noted that Lance Armstrong started with the successor team, Team Motorola, that took over this bicycle team after Southland ended its sponsorship - but wanting to know more Lance-history wouldn't be a motivation for reading this; he is only mentioned a few times in passing.

Closing Four Mile Run I-395 Underpass

395 Flood Danger
Approaching underpass to I-395 from Shirlington side, Friday commute

After considerable amounts of rain overnight, Four Mile Run apparently flooded the bike path underpass for I-395.  By the time that I arrived on my commute, around 7 am, I think the flooding was already gone but I chose not to investigate and rode around (the old way, over 395 on the pedestrian bridge and down Martha Custis).

In the evening the barriers had not been "officially" removed but someone had pushed them aside.

The Wheel-Spam Comment Game

Spam Blog Comment
Example of a "comment" linking to a commercial tire site from Prolix

Apparently because bicycles have tires, Prolix (and some other identities that I think are the same person) regularly post "comments" that feature links to several different automotive tire sales sites. Because this blog is pretty low-traffic (900-1,000 page views per month, most from Google searches) it seems an utter waste of time for this person (or bot?) to be doing this, but we're only talking about my removing 2-3 comments per week, typically.

Does someone get paid for this? Presumably not on the basis of how many links are placed but rather according to how much traffic it creates. How boring.

Here the syntax is OK and the comment more or less makes sense (although this is the fourth or fifth time I've read "my very first comment on your site" from Prolix) but given the wording of some of the others, I'm doubtful the person doing this has English as his or her first language. Not that it matters, but it seems that much more crazy that somewhere in the world some person is searching for tire-related blogs in a foreign language to place phoney-baloney comments for car tires in Florida in order to make a living.

Cyclists with Guns Chase Car (Washington, DC)

Short Washington Post article titled "Bicycles open fire near Capitol Hill" - "Two people on bicycles fired shots as they pursued a car late Saturday in a Northeast Washington neighborhood on the edge of Capitol Hill, authorities said."

The police admit no understanding of the motive, but divine that "it did not appear to be a random attack." Their solution? "Officers will patrol the area and will give special attention to people on bicycles as well as to enforcing traffic regulations, police said."

The attention grabbing "near Capitol Hill" does not mean they were riding around the Capitol itself shooting guns from bikes - they were more than a mile from the U.S. Capitol.

Bicycles to Africa

Once again, my Google news alert brings in an interesting item, a story about a Danish bicycle approach to providing developmental assistance through bicycles to Africa. There are various approaches to this that I am familiar with. In an earlier post about an article about the "Team Rwanda" cycling team there was mention that the attempt to provide bicycles suitable for that country was hindered by the high cost of getting the parts there.

Baisikeli
The Baisikeli Company in Denmark - "Baisikeli" is "bicycles" in Swahili

The Baisikeli company has a model that does not give the bikes away but sells them.
Baisikeli works towards developing the bicycle industry in the developing world. Bicycles are important in poor areas because with cheaper and better transportation opportunities, people living in poverty can increase their income and get access to education and health care.

In Denmark, Baisikeli collects used bicycles and ship them to Mozambique and Sierra Leone where they are repaired and sold. All expenses in Denmark are financed through the two bike shops in Copenhagen; so all the money earned in Africa can be reinvested in developing the workshops into producing their own bikes.
This is quite different than a model that gathers cast-off bicycles, ships them to Africa, and gives them away. Also, since they are (I think this is correct) primarily shipping bicycles that they have themselves used in their businesses, the types of bicycles sent to Africa are of fewer different types.

Baisikeli - cykler for et bedre liv from Henrik Mortensen on Vimeo.


Alas, there is nothing in this world that is perfect - in looking around on Flickr for photos related to Baisikeli, they seem to have gotten into a problem with a Dutch company that claims they copied one of their cargo bike designs for a bike that is rented to businesses in Denmark for three years and then will be shipped and sold in Sierra Leone and Mozambique.

The (apparent) Baisikeli copy of the Workcycles bike

I am sympathetic to the Workcycles complaint that "the unique frame geometry and structural elements have been copied to the millimeter, while about a dozen cosmetic changes have been made to dodge legal protection" but put off by the remark that "it also happens to be very crudely made, unlike our real Fr8." If the Baisikeli people could have gotten permission to use the design that would have been a better approach but one doubts that a bike built to the Workcycles standard would be useful for this business model in Africa for various cost-related reasons.

Hmmm.

Complex Landscape of Bicycle Safety

My Google "news alert" for news items on the Internet about bicycles brings a strange collection of cycling safety-related items this morning.

A short article in the Economist takes the lesson from commuter cyclist Michael Wang's fatal accident in Seattle (actually, from three recent fatal cyclist acidents in the Seattle area) that, "with a very few exceptions, America is no place for cyclists" because it isn't safe - "dying while cycling is three to five times more likely in America than in Denmark, Germany or the Netherlands."

The article concludes that traffic calming, dedicated cycle tracks, and stop lights and traffic laws that favor cyclists work together to create a safer environment for cycling. Portland, Oregon is given credit for following this approach while Seattle flunks - "Nearly 6% of commuters bike to work in Portland, the highest proportion in America. But in five out of the past ten years there have been no cycling deaths there. In the nearby Seattle area, where cycling is popular but traffic calming is not, three cyclists have been killed in the past few weeks."

Meanwhile a Danish design award, in the category of "play," was given to the Hovding "airbag helmet," from Sweden. (I did a short blog post about this helmet earlier when it garnered attention for its unusual approach.) The designers of this "helmet" (that inflates on impact from a collar) won 100,000 Euros! The problem this "helmet" solves is that, "people would rather get hurt than mess up their hair." And a typical helmet may be "too sporty" for the rider's particular sense of style. The theory is that a significant number of these helmet-refuseniks will then buy these 500 dollar helmet-substitute collars (that appear to require recharging, among other issues). Some statistics related to head injuries and fatalities in western Europe are tossed in to support the need for this product. (For the same countries that the Economist says are safe.)



The Danish design committee seems completely at odds with the Dutch cyclists interviewed in this 2011 video who were asked about cycling and helmets - they seem to regard their everyday cycling as entirely safe, and most state they would refuse to wear helmets if required to (much less a rechargable helmet-like collar that costs as much as ten helmets). They are asked when they started cycling (typically, at age three-four), why they use a bicycle for transport (a not-very-surprising list, from "good for the environment" to "less expensive" etc.), how many days per week (typically five to seven), and "why don't you wear a helmet." The answers to this question are much more varied, but do include "because I look like crap" but also (my favorite) "because only Germans do that" and "it's safe without" and "it's very safe."

The last question is whether the person would wear a helmet if it became required by law in Holland - the typical answer is "no" with some explanations such as "you really don't need one" and "you (the typical cyclist) are not traveling very fast." One commented (after indicating she would follow the law) that "I don't think I would ride so often then." (The Australian doing the interview also asked if a Dutch cyclist, visiting Australia, would follow their helmet law - but the answers weren't so interesting to that one.)

This is a somewhat disjoint post, I realize - but then so is much of my thinking about this topic. No more disjoint than the reality of cycling safety, I suspect.

Maxim Gun & Tricycle (1901)

Maxim Gun & Tricycle (1901)

From a Scientific American supplement article, 1901
BICYCLE ARTILLERY.

The bicycle artillery corps is a body of recent creation which seems to be destined for a great future. In fact, it is now in a fair way of doing reconnoissance duty in place of the cavalry. How much superior, indeed, is a bicyclist to a horseman. He is always ready to start immediately, while the latter has to wait to harness and saddle his steed. Then, again, the bicycle is faster than the horse, and requires less care; and the fact that no food is needed constitutes an appreciable advantage in a campaign in which so many difficulties are met with in the way of procuring forage. It is true that the bicycle can be used only upon roads, but in France and Germany the byroads, large and small, are so accessible that the use of it is capable of being made general.
. . . . .
Such considerations have led the large English house of Vickers, Sons & Maxim to devise a machine gun tricycle, which we represent in the accompanying engravings. Two Maxim guns are mounted upon the tricycle, the weight of which is 120 pounds, while that of the two guns is 54, that of the tripods 106, that of the spare pieces 8, and that of the 1,000 cartridges, with their case, 86. This constitutes a total weight of 374 pounds, to which is to be added that of the two men who ride the vehicle. It seems that such a tricycle is capable of running at a high rate of speed upon a level. Upon up-grades, however, it is necessary to dismount and push the machine.

A Better Kickstarter Bicycle Product Proposal

In two earlier posts, I looked at three other Kickstarter proposals for new bicycle products. Most recently, I looked at a proposal for a self-inflating bike tire that I thought was silly - are people that lazy that they need this produce?? (Also, they are trying to raise $250,000 - WOW.)

Before that I looked at two safety-related bicycle add-ons both based on the "biking is dangerous - let's make it safer" way of thinking about cycling.

There is also a proposal for Flipphandle, a product that simplifies bicycle storage by making it easy ("at the push of a button") to turn the handlebars 90 degrees from center so that they line up with the bike frame.



I like this idea a lot, although I have a few problems with its presentation in Kickstarter. For one thing, the video and photos always show a straight handlebar bike, which would be the kind that presumably benefits the most from this device. But what about bikes with "traditional" handlebars? It would seem that they would benefit somewhat too, but the Kickstarter come-on should either show the produce with this kind of handlebars or clarify that the product is only aimed at part of the bicycle market, those with straight handlebars. (My assumption is that the drop-handlebar crowd would not want be interested in this feature even if there was some small benefit.)

Really though I wonder about the audience for this - do they expect to sell this through bike stores and the Internet as an aftermarket product? Because I don't have a sense that most people invest like that in their bikes. What would be great is if a bike company with "urban" bikes with straight bars would add this to a bike or bikes they sell, if only as an option.

In the Flipphandle comments it says that they are looking to develop folding pedals as well. This makes a lot of sense as a tie-in with the folding handlebars if you are thinking of this more as a solution for walking a bike in tight situations and less as a solution for storage. For one thing, anyone who walks her or his bike much, particularly with standard platform pedals, has had the unpleasant experience of banging some part of a leg against a pedal, which considering the design of many such pedals can be painful. A bike with folding handlebars and folding pedals would be much easier to maneuver in a subway car as shown in the video than one with just folding handlebars.

For whatever reason, they don't seem to have much chance of raising the necessary money at the rate they are going. And I certainly don't need one - I have three bikes with drop handlebars and one mountain bike used 3-5 times a year to ride in snow.

More Kickstarter Bicycle Improvement Possibilities

Kickstarter is "the largest funding platform for creative projects in the world" (they say) and it turns out, some of these opportunities are for new products to make cycling safer or easier (and hopefully more popular). In a previous post I looked at a couple of modestly scaled money raising endeavors for safety lighting proposals. Thanks to tire that inflates itself as you ride. They only need $250,000 (yes, a quarter of a million dollars) to get this under production!



It's a clever idea - there is a small tube that runs around the entire tire right in the middle of where the tire contacts the ground and as the bike compresses this tube, air if forced through the valve into the tire until some previously set limit is reached, then it stops. If the pressure goes down, it pumps it back up.

Of course there are many clever ideas that are patented that don't enjoy commercial success for one reason or another. What about this idea?

The problem that the inventor is trying to solve is simple enough - bike riders should be able to jump on their bikes and ride off knowing that the tire will soon be inflated to the right pressure if some air has escaped since the last time the bike was used. It is not an anti-flat system that would say pump the tire up fast enough to keep ahead of a lead created by a nail (for example). It also solves the problem of having your tires always at a consistend pressure as you ride since I don't think anyone has ever argued that the small amount that this happens is actually a problem for anyone. Therefore your user is the person who is tired of pumping air in her or his bike tires once in a while before riding.

Are their many such people, really? One wonders. For one thing, while it is not a good thing, many people who ride even relatively frequently (for Americans) are rather lax about their tire pressure, based on conversations I have had. Those people who do care about it, it seems to me, are not likely to feel a desire to turn this activity over to an automatic system to do it for them.

Efforts to keep air in the tires or avoid having flats have been proposed (and patented) since the development of the safety bike in the 1880s, so attempts to simplify cycling by reducing interactions with tires are not new. For example, below is an 1896 patent for a "self sealing" bike tire.

Self Sealing Bike Tire Patent (1895)
Patent 551,408, the self sealing tire

Why didn't the self sealing tire succeed? Well, because it was a layer of complexity and cost on top of what is the best thing about bicycles - that they are pretty simple devices. And also that they introduced a new failure "opportunity" rather than just getting rid of the old one. And of course you have to pay more for it.

This particular idea is quite elegant (in a way) but the Kickstarter proposal fails to suggest what the price point is that they have in mind for these fancy tires that inflate themselves. While in theory anyone would say, "sure I want a tire that keeps itself at the right air pressure" I suspect when they see the relative cost they will wonder if operating the pump occasionally is really that inconvenient (for that portion of the cycling public who care about their tire inflatiion situation other than when the tire is more or less flat). That, in the end, is the issue - are people (Americans - I assume a Dutchman for example would guffaw if he saw this product) so lazy that they will pay $$$ more for a high priced tire rather than fill it with air occasionally themselves? The product developers don't argue that it is a safety issue, unlike that yellow light in your Ford Explorer so you don't tip the thing over with underinflated tires.

And I'm pretty sure, notwithstanding their remarks in the FAQ, that this approach does introduce new problems to manage. They claim that a "little filter" will keep dust and dirt from interfering with the intake of air to inflate the tire, but given where it is (down practically on the ground) and the small sizes, presumably then the issue is the "little filter" getting a lot clogged. Also, as shown in its development phase, this pressure gauge limiter thing that rides on top of the inner tube valve looks like trouble with a capital "T". They admit in their FAQ that in production this thing would ideally be a lot smaller and perhaps not angled straight out from the rim but rather along the rim somehow, or supported by a spoke. Well - yeah. Because a weak point in every inner tube is at the valve, so putting that big monster thing on top of the valve is begging for trouble. They don't need just their own tire, I think, but their own wheel-tire combo.

Finally, the tube (they call it a "lumen" which apparently is a biology term for a tube-like structure) that is compressed as the wheel turns and does the pumping runs on the outer center of the tire where the greatest wear is on any bike tire. However thick the wall of that lumen (tube) is is how long your tire lasts. If you get a little cut through that lumen - well, so much for the self inflating feature and the tire is ruined (which they admit in their FAQ). So, for a given style of tire, this self inflating tire costs more but lasts a shorter period of time and has a risk factor for the failure of the feature that you paid extra for.

Industry statistics don't say how many bicycle tires are sold, but presumably the best result for the inventors would be to get a nice urban bike equipped with these tires as standard equipment. Perhaps they'll get lucky.

Anything that makes riding a bike easier can be considered, if you are in the cycling camp, to be good for society (more green, more exercise, etc.). This is something that replaces one small inoffensive task (that many are a bit inattentive to, but with few serious consequences) with unnecessary complexity and cost, and then claims to be easier. I guess it depends how you define "easier."

That's enough Kickstarter bike projects for today.

Knack Cycling for Everyone - Book Review

Cycling for Everyone - A Guide to Road, Mountain, and Commuter Biking by Leah Garcia and Jilayne Lovejoy (Knack, 2010) is lovely to look through and reflects considerable effort, but I'm not sure that it is "the ideal new resource for anyone looking to get introduced, or reintroduced, to today's world of cycling" (as it says on the rear cover).

Amazon has a "look inside" link for its page for this book so you can get a fairly good sense of what the book is like.

What's good:

* More than 400 photographs - it must have been a major effort just to figure out and produce all of these; it's a fun book to page through.

* Certainly introduces at a high level many issues connected to cycling.

* Presents some topics quite well when the book's format (that seems to be part of the Knack series) provides the right amount of space.

What's not-so-good:

* Typically one photo is all that is provided for any particular issue, even for the description of maintenance activities where a sequence would be more helpful. In this regard, the extremely structured format of the book works against it.

* The highly structured format for each page also means that there can't be much detail written about any particular subject - for the most part each subject is dealt with in two facing pages.

* Despite being an introduction to the subject, it often reads as though you already know something about the subject - in the summary of what makes a road bike a road bike, it says "uses 700c wheels, caliper brakes, and skinny smooth tires" - skinny smooth tires is clear, anyway.

* Doesn't answer many "why" questions. Again, due to the limited space for text, much of what is provided are descriptions without explanation.

* The glossary is too short and misses many terms used in the text without explanation, and is the one part of the book with no images. In the text one is told to avoid potholes to avoid getting "pinchflats" which are just one item not in the glossary (or the index, for that matter).

I concluded that there is far more to cycling than I had realized since it doesn't turn out to be possible to provide anything like a comprehensive introductory guide to the different types of cycling (mountain, road, commuting) in a single book.

I was somewhat amused by the subjects where the authors chose to provide additional information - since they live in Colorado, they are quite a bit more into mountain biking than commuting by bike so unlike most subjects that must be dealt with in two pages, you get "terrain tips - part 1" and "terrain tips - part 2" (or four pages!) on handling rough riding on a mountain bike. (The coverage of bike commuting in this book is weak, when you get down to it.)

And they are pretty much satisfied with the modern buy-lots-of-crap-and-keep-corporations-afloat approach to cycling - this is most noticable in their discussion of winter clothing, where wool sweaters you might already own are not mentioned - the models are attired in hundreds of dollars of special cycling clothing. (Don't get me wrong, I happen to take that approach too, but I'm pretty sure it isn't the most cost effective and I sure didn't start that way.) I think this reflects a lack of enthusiasm for true beginning bike commuters - mountain biking is more fun.

Summary - it's a pretty book to look at, and has it's tidbits of useful info here and there. It isn't a particularly useful comprehensive introduction.

1899 "Book on Wheeling" & Tandem Photographs

Neesen Title Page
Title page of Dr. Neesen's Book on Wheeling

Dr. Neesen's Book on Wheeling is a rather extreme (and late, since the cycling craze was ending by this time) example of the "physician as guide to all-things-cycling" approach to cycling advice. Note his particular qualifications as a specialist in women's medicine:
Assistant to the Chair of Gynecology, Long Island College
Hospital ; Member Women's Hospital Society ; Kings Co. Medical Society, Long Island Medical Society, Kings Co. Medical Association ; Lately House Surgeon at the Woman's Hospital in the State of New York ; Recently House Surgeon at Prof. Martin's Privat-Anstalt in Berlin ; Member Physical Education Society of New York.
He includes some interesting photographs of men and women cyclists in his book - here are those of tandems and riders. I have included the original captions, which in keeping with his rather directive sort of advice, usually find some fault with the models' posture.

Diamond Frame Tandem

Above is the only photograph in the book of this particular tandem - although the front rider is a woman, the frame has a continuous top tube rather than a step-through portion for the woman rider, which could be either the front section or the rear. (This author takes the slightly radical position that women, properly attired, should be fine riding a "diamond frame wheel.")

"Combination" Tandem

Above is the first of two photos of this tandem that has a step-through frame section in front. Note that this tandem (and the preceding) have the ability for the back cyclist to steer also - how this worked in practice, one can only wonder. It certainly negated some of the advantage in the normal tandem arrangement, where the "stoker" in the rear can focus all if his (or her) energy on pedaling. Presumably the assumption was that the man could easily see over the woman in front, but it doesn't look that way here. Many tandems at the time had the step-through portion in the rear, in which case the rear rider could not steer (at least not in examples I've seen). There was an apparent tension between the version that was more socially acceptable (woman in front) versus what was easier to engineer (man in front).

Women on Tandem

To ride a "diamond frame wheel" Dr. Neesen advises wearing a short divided skirt, but apparently this is too short.

Increased Visibility, Increased Safety?

Project Aura: Bicycle Safety Lighting System from Project AURA on Vimeo.

Project Aura is a clever idea to increase the visibility of cyclists at night, particularly from the side. Since the system is driven by the wheels spinning, they added in a feature that the lighting changes from white to red when the bike slows down, something like a brake light on a car, although not facing to the rear.

As can be seen from the video, it's a dramatic lighting system. In order to focus attention on the Aura system, the video of the bike at night includes no headlight and no rear reflector, although their Vimeo page notes that "By law (in Pennsylvania, the laws vary state by state) a front headlamp and rear reflector are required, use of a rear blinky is up to the rider's discretion."

I have two problems with this thing - first, when you look at Aura's other information, it is clear that this isn't a particularly simple system - having a spinning light system attached to both wheels for a typical cyclist would be a big pain to maintain, adding needless weight and maintenance issues (not to mention cost) to what is, in the end, the delightful simplicity of a typical bike. Moreover there can be too much of a good thing - making the bike this visible by jazzing it up like this could be a traffic distraction. For motor vehicles there are laws about such things - you have to have certain lights, but you can't bolt lights of any color and type all over your car. It does seem wise to have your bike highly visible at night from the sides; the easiest way to achieve this seems to be to wear something visible and reflectorized on your upper body.

MonkeyLectric from Jade Ajani on Vimeo.

Apparently there are 'arty' spoke lighting systems with a focus more on misguided bike bling than safety.

All of that is better than a home lighting system that is "pendant lights . . . constructed with spokes and hubs remaining from the destruction of bike rims." I guess if you don't stay out of accidents with good lighting, your ride can become a lighting system itself. Weird.

Carbon vs Steel for Bike to Cross USA

Bruce Weber, a journalist for the NY Times, is at age 57 "recreating" an earlier cross country bike trip and is writing a serious of articles (and blog entries, and tweets, and ... and ...) about it. Also, given the nature of things, there is an "interactive" map that charts his progress.

To summarize his article in the Sunday NY Times today - it's been hard going so far. For better or worse, now many people can offer advice that is shared with all of us. The NY Times featured seven "emblematic" comments from the hundreds made so far, one of which suggests that it's his steel bike that's the problem.
I ride a lot. My best road bike cost $14,000 (custom full-carbon). I think you’re underserved by a steel bike. But then, I’m old (75), though I do log 5,000 miles per year cycling, in the U.S. and Europe.
The suggestion seems to be that an expensive carbon fiber frame bike would be better for this activity than the (presumed not expensive) steel frame bike. I do not believe that it is necessary to spend anything like that much money on a bike suitable for this and I strongly believe most carbon fiber bikes would be a poor choice for what Mr. Weber is doing.

Detroit Lake 300K August 2, 2008 002
A steel randonneuring bike, based on a 1982 steel bike frame

Looking at the second issue first - I wonder if the writer understands what Mr. Weber is doing. If you are on a supported ride, when your baggage is carried by a support team in motor vehicles (and all the meals arranged in advance, and so on) then riding a carbon fiber road bike would be great. Here however the rider is carrying everything with him in panniers, and the traditional (and seemingly reasonable) approach to that is to ride a randonneuring or touring bicycle, made of steel. You sacrifice some weight for the cycle in favor of strength as well as a bicycle geometry more suitable for hauling weight long distances reliably and comfortably over pure speed. It's simple, really - touring bikes are made of steel. And this is a touring bike situation.

As to cost, that's a different matter - certainly one can spend thousands (even more than $15,000 for one custom built by a builder who produces them one at a time) on a high-end steel touring bike - I would chose something like this Co-Motion steel touring bike (at around $3,500). The example in the photograph (that could have a rack and panniers added easily enough) is based on a steel frame exactly like one I bought on eBay for $117 (including shipping!) that one could then kit out in a suitable way for another thousand dollars or so. I tend to think that Mr. Carbon-Fiber-is-Best is partially correct that for a bike to ride across America, Mr. Weber has underspent in dollars and is paying for it otherwise. And eventually will pay for various fixes such that it would have been less expensive to buy a more expensive - and suitable - bike right at the start. He has already replaced the cassette with one that has cogs more suitable for climbing hills at slow speed, for example. Many other components on a lesser bike will have a predictable service life less than the distance represented by a cross country ride.

I have not been able to work out exactly what sort of bike Mr. Weber is riding - the photos seem (purposely?) to obscure that information. The type of bike, however, is obvious enough - it is the kind of "not a mountain bike, not a road bike, but what is it bike" that one sees around town often enough. Riding across the country seems like an activity for a purpose-built bicycle.

Bob Roll's "Two" Books

Roll on a Murray
Bob Roll in his days with the 7-Eleven team

Lately I have given up Swedish detective novels (of which there seems to be a never-ending supply) in favor of cycling books of various sorts, from "policy tomes" (think Pedaling Revolution: How Cyclists Are Changing American Cities) to cycling travel narratives (now I'm reading Take a Seat: One Man, One Tandem and Twenty Thousand Miles of Possibilities and also the occasional book about professional cycle racing.

Which brings me to Bob Roll, and his "two" books. Bob Roll has been a cycle racing commentator for OLN and more recently Versus for the Tour de France following his racing career, but his first sports journalism efforts were writing for Velonews.

I work in a very large library in Washington DC. We don't have everything, but we have quite a lot (of books, anyway). Given Roll's performances for "Road-ID" ads (you can watch the regular ads on the Road-ID channel on YouTube, although you get the best sense of Bob during the first third of this "outtakes" collection video. He even talks about his books, saying, "I am an author - although the books aren't that good." He was joking.

So it seems plausible that a book by Bob Roll could be pretty funny. And, according to the very large database at the library where I work, Bob has written two "memoir" type books of his racing career! (Leaving aside two books he has co-written that are "how to understand the Tour de France" guides.) Fantastic!

Bobke One book record
The "bibliographic record" that describes Bob Roll's first book, from the very large database of such things

So, above is the description of Bob's first book, published in 1995 - 124 pages of Bob. It's a fun book, in a large paperback format with quite a few photos of Bob being amusing, or sometimes just racing his bike (without being amusing). Most of the text is taken from stuff he wrote for Velonews and is in the form of cycling race diary entries (he was writing while still racing at that point). It's a little random in spots.
Lourdes is a bizarre place. It's a sort of Kmart for Catholics, and provided a weird takeoff point for this final mountain stage.
And like that. So a little random.

Nevertheless, if in the right frame of mind, Bobke I (as I think of it) is a good (and quick) read.

Bobke II book record
The "bibliographic record" that describes Bob Roll's "second" book, from the very large database

Why do I put "second" in quotes?? Because once I got my hands on the "second" book and started reading, I thought, "wait a second, I read this book already!" And I had, mostly. The first two thirds of Bobke II is the same as Bobke I, except that it is now in a smaller paperback format (with more pages, yeah) and no photographs (boo! on taking out the photographs). And in fact, on the verso (that's "back side" for non-librarians) of the title page it says, "Part I [of Bobke II] was previously published as Bobke (VeloPress, 1995)." So, what one gets that is new in Bobke II is "Part II (of Bobke II)" and that amounts to about 65 pages. To paraphrase Bob, "ouch!"

Still, there is some good stuff in those 65 pages. There is a description of Bob's training rides in North Carolina with Lance Armstrong and there is probably the most amusing article-length first person description of a professional road race that I have ever read anywhere, although I may be heavily influenced by the central role of the Russian "Team Lada" cycle team in it. (I have some college degrees in Russian studies. Oh - and somewhat oddly, the full text of this story is online.)

I assume the reason that the publisher decided they could get away with this is that the number of copies of Bobke I printed and sold was tiny - at that time, the only reason anyone would know who Bob Roll was would be from being a bike racing nut (remember, 1995 was before Lance Armstrong won any Tours) and (or maybe or) reading Velonews. This isn't a huge market. By the time of Bobke II, in 2003, Bob had already put in several years as a TV commentator and although the audience was still skewed to people who were interested in cycling, thanks to Lance this was much larger market - so for the three people who accidentally bought Bobke II who already had Bobke I; well, they should be more careful.

I feel some affinity for Bob Roll, although for no good reason I suppose. Bob has a gap-toothed smile and I have a gap-toothed smile. Parked in that gap-toothed smile Bob has a tooth that (from the color) I would guess has a dead nerve and guess what, so do I. Bob thinks he's pretty funny and I would like to think I'm funny (but I concede wacky crazy funny to Bob). And Bob is a former professional bicycle racer and I like to sit on a bicycle from time to time and pedal to and from work.

At any rate, I hope I have cleared up the "two Bob Roll memoirs" situation sufficiently.

If after all this, you are still interested in some further amusement, I offer a link to a 1987 video from the 7 Eleven Cycling Team that I came upon while doing "research" for this blog post.

Springer watches 7 Eleven team
At 2:18 during this very dated video there are a couple of seconds of this Springer, attentively watching the bicycle race. This would be Springer with different interests than the one in our house.

Annual Dillons Bus Photo Op

Dillons bus splits lane
Dillons bus driver demonstrating his "split the lane" right turn technique

This is just lazy driving, in my view. But I only drove a city bus for 12 years so what do I know.

Anyway, as with a year ago when I saw some less than excellent driving from these people, I took a photo and then I wrote an email:
This was taken with a cell phone camera, so the quality is not terribly good. This is proceeding west in Independence Ave SW, just approaching the intersection at 7th SW. This would have been around 4:30-4:40? Today. I don't wear a watch.

This is a common practice with Dillons buses making this turn - splitting the two right lanes. Here you have a photograph illustrating what I see often enough. It's just sloppy and dangerous - and completely unnecessary! This bus is turning into three lanes, so if the bus was entirely in the right lane on Independence it would be no problem to swing around the corner even if the nearest southbound lane has a vehicle in it. The bus ain't that long.

The only reason for this approach is to make it simpler to intimidate pedestrians by having four-five feet to turn in the direction of the crosswalk to the right without actually going into the crosswalk. I grant you, waiting until the crosswalk clears if the bus stays patiently in the right lane, where it belongs, isn't much fun - but what this driver is doing is putting the problem in the lap of everyone in two lanes behind the bus. Do you want your buses sideswiped? This is asking for it.

I was on a bicycle, by the way, and had plenty of room to ride right by (on the left) and from my personal perspective this is great since he blocked traffic and I got on down the road. But otherwise it's awful.


Stupid bus driver
The last time I took a picture of a Dillons bus - the "open the door with a full lane open to the right so the passengers can get run over" technique

Little Lost CaBi Bike

Cabi Bike One
Unlocked, in front of the U.S. Botanic Garden, middle of the day

I went for a mid-day run and below the Capitol (in Washington DC) this CaBi bikeshare bike was sitting like this, unlocked, in front of the U.S. Botanic Garden. No one around seemed connected with it. CaBi bikes don't come with locks - the idea is you ride from one docking station to another, so why do you need a lock? On the other hand, if someone makes off with one charged to a particular account, there is a 1,000 dollar charge.


Cabi Bike Two
Still here twenty minutes or so later, but someone stood it up anyway

When I was heading back, it was still here. That someone had stood the thing up led me to think it really was here unattended. It now had some tourist brochures shoved in behind the seatpost. My guess would be that someone found it improperly docked (not locked in) and took it for a little joy ride. I called CaBi (their number is on the bike) and they were going to send someone to investigate - nobody around paid the slightest attention to my interest in this bike - if someone had really left it like this, out of their sight, the person was being a bit lax.

A problem for CaBi would be that this area is restricted for delivery sorts of trucks, like the one CaBi uses to ferry bikes around. Someone would have to walk a few blocks.

Later in the day when I went home it was gone.

Springs, Not Air, for Bike Tires (1896 Patents)

For whatever reason, in December of 1896, more than one clever (or not so clever) inventor decided that they could make their fortune with a tire that required no air (or at least was only optionally inflatable). All three of the patent applications below were made with one month ~

Patent 573907
Patent number 573,907

The patent above is straightforward in intent:
This invention relates to tires, being especially designed for use upon bicycles and other vehicles, and the object in view is to provide a mechanical tire resembling in action a cushion or pneumatic tire, the elasticity being obtained through the medium of a series of springs disposed around the wheel-rim and incased within a suitable sheath or cover, thus dispensing with the necessity for a pneumatic tire and avoiding the disadvantages of frequent puncturing and repair incident to the use of pneumatic tires.
The design is simple enough - one wonders if the inventor built a prototype that worked. Why are we still riding around on tires filled with troublesome air?

Patent 573920 (part a)

Patent number 573,920, part a

The next submission to the Patent Office seems to have decided a more complex approach was called for - in fact, he patented two separate spring systems as possible ways to solve the problem. (See above, and below.)

Patent 573920 (part b)

Patent number 573,920, part b

Just before 1896 ended, we have the submission below - the simplest approach yet. The inventor takes a more middle of the road approach - air is optional, not required:
If preferred, my improved tire may be used without being inflated, the spring D serving to maintain the tire in its proper position and to give elasticity thereto; but said tire may also be inflated with air in the usual manner, if desired, and by the usual means, and in this event both the air and the spring serves to give elasticity to the tire and to maintain it in the proper form.

Patent 574015
Patent number 574,015

Alas, 115 years on, we are still riding around on tires that get punctures.

Is Cycling Safe? The Product Development View

Since I ride a bike more than a 100 miles a week on average, I think about bike safety a bit. Mostly I ride on bike paths or bike trails (or whatever they are properly called) although of course they are used by pedestrians, runners, etc - but not motor vehicles! And it is the motor vehicles that represent the significant safety problem for cyclists.

In the Seattle area, supposedly a very bike friendly region, two middle-aged cyclists were recently killed within a period of less than two weeks, one by a truck that went onto the shoulder where the cyclist was riding and another when an SUV made a left turn once oncoming car traffic had cleared, but not the oncoming cyclist. (In the second case, the driver got out, ascertained there was an accident, then drove away - hit and run.) Even though I read about cyclists getting killed all the time, for some reason these two events bother me.

At a conference recently (that had nothing to do with cycling) I heard a presentation by someone from Kickstarter, an organization (well, it's a commmercial company, actually) that provides a vehicle for getting start-up funding for various kinds of endeavors through their web site. Many are small cultural projects but others are efforts to start sales of products of one sort or another.

As it happens, Mr. Bikesnob NYC had a recent blog entry about a Kickstarter project for a bike turn signal system that is built into a left cycling glove. Kickstarter seeks solicitation primarily through videos; the "you turn" fundraiser video is below.



Mr. Bikesnob has lots of fun spoofing this Kickstarter video in various ways, although he leaves aside the main question I had (at first) which is whether the fellow is serious - the circuitry in the glove detects whether the cyclist points his hand up (for a right turn) or out to the left (for a left turn) and activates one of two LED arrows built into the glove. Yes, but . . . we inherited the "left hand straight up = right turn" thing from people driving cars (from when turn signals for cars were not always present!) and most cyclists now use their right arms to signal right turns. Since the left brake lever is for the front brake (also known as the brake that works best) I never signal right turns with my left hand - common sense dictates using my right hand to signal, stuck out to the right, and keeping my left hand on that brake lever. So if you wanted LED turn signals combined with gloves, it would be simplest to put a single arrow on each glove - assuming you think it makes sense to have such digital signals at all.

But I digress.

The real question I have is whether attempts to buttress cyclists' safety through developing new products to buy and use is a good approach. That it is an American approach, that much is obvious, but is it going to make it safer for cyclists?

Frankly I'm doubtful. The two things I believe that are needed to improve the safety of people on bicycles (vis a vis cars, trucks, etc.) is more people on bicycles, which inevitably leads to a lower accident rate for the cyclists; and, in tandem with that, a change in our transportation culture such that the "complete streets" concept makes sense to more and more people.

Of course, common sense says that cyclists are safer when they are visible to motorists if they use roads. (And of course there are laws requiring reflectors, lights, etc. for certain conditions.) This product, however, seems to contribute more to making cyclists more car-like, which doesn't seem particularly helpful. An LED turn signal system for bicycles contributes mostly to making cycling seem more dangerous and more complicated than it should be. The more safety equipment we pile onto cyclists, the less appealing it becomes, thus defeating the "more cyclists = fewer accidents" strategy.

Kickstarter has another cycling funding project - a bicycle brake light system.



It is suggested that having a brake light like a car's (that comes on when the brakes are applied) "has the potential to save many lives." As with the glove-signal system, it seems more to add to the complexity of cycling and to the impression that it is dangerous. Having a light or lights and a reflector to make a cyclist visible when it is dark and to take other measures to increase one's visibility to motorists makes good common sense but "I failed to realize the bicycle was stopping and therefore ran into it" isn't the problem I read about with cyclists hit by cars from the rear, it's the "I wasn't expecting a cyclist at that location, I didn't see him/her, and . . . " situations that are the problem. As the number of cyclists increases, the motorists get used to them, and expect to interact with them in their daily drives (and stop running into them so much). Also, eventually (a la Amsterdam) more and more drivers will be sometimes-cyclists, which can only help.

Now I'll get off my soapbox, such as it is. I'll put forth my thinking on bicycle helmets another time . . .

PS I asked a fellow from the Netherlands recently if he commuted by bike to work on Capitol Hill - his answer? "No, so many here talk about friends they know who got killed riding their bikes. No one in the Netherlands is ever killed riding their bike! It seems too dangerous."

Ideas for Bicycle Saddles (1896)

Google presents zillions of digitized patent applications - in the 1890s there were so many patent applications related to cycling that there was magazine, Cycling Monthly, that was nothing but patent and trademark applications related to bicycles. Not surprisingly it is more entertaining to page through that (if one works in a large library where there are some issues) and then bring up the Google versions rather than try to find 1890s patent applications for bicycle stuff directly in Google.

One quickly realizes that then as now, there is a sense that there must be a better bicycle saddle. The following examples are all from 1896 ~

Patent for Bike Saddle 554337
Patent number 554,337

The notion in the above "invention" is that really you just want to sit on a couple of springs.


Patent for Bike Saddle 556250
Patent number 556,250

Above is something like the opposite view to the previous patent - no, what you really want to do is sit on a shaped piece of wood! Oh, with a slit in the middle.


Patent for Bike Saddle 557238
Patent number 557,238

Above, the well-known view even today (perhaps even more so today) that a wider base of support is key.

Patent for Bike Saddle 558917
Patent number 558,917

A rather complex contoured approach . . .


Patent for Bike Saddle 562919
Patent number 562,919

The last example here (but hardly the last patent application for bicycle saddles from 1896) is an "add on" to an existing saddle the would provide inflatable cushions held in place by their invention.

Bicycle "Body Shield" (Patent, 1896)

Patent from Google that demonstrates that while the basic bicycle design hasn't changed much, ideas for how to improve cycling have had their ups and downs.

Bicycle Body Shield Patent, 1896
Has every crazy idea been patented?

The object of the invention is to provide a new and improved body-shield more especially designed for use by bicyclists,boatmen, or other persons exposed to the force of the wind, the shield being arranged to not only break the force of the wind against the body of a bicycle-rider, but also to protect the throat, breast, face, and ears of the rider and at the same time permit the rider to easily get on or off the bicycle.

Plastic Bike Design

Recycled plastic bicycle design - this seems pretty clever but I have my doubts as to how pleasant it would be to ride.

None of the comments seem to have been made by anyone who knows much about bicycle design.

The first thing I see is that the steering tube is quite upright, which might be fine for a racing bike but for something like this, it would make it twitchy and requiring more attention to control. It doesn't help that the handlebars are so short.

Can this really not have any metal in it? It would be pretty amazing if you could have crank arms (that connect the drive system to the pedals) that are just made out of plastic that would support an adults weight and transfer power reliably.

It appears that the pedals are relatively spread apart - usually there isn't much variance in the distance left and right of center that the pedals are. A larger distance ("Q factor") is apparently less efficient.

Is the height of the seat adjustable? Doesn't seem like it. That's probably the biggest problem.

Park Service "Waters" Bikers, Joggers

Sprinklers at Hains Point
The roadway is wet, the bikers and joggers are wet

The National Park Service runs a pipe along the roadway of Hains Point and uses pumps to pull river water into a large scale sprinkler system - in their effort to water both sides of the roadway, they blast the water across the roadway, too. From time to time one gets a blast in the face - it's a little strange. Since it's hot, it has its positive aspects, but on balance I would rather not have this experience too often.

Sprinklers at Hains Point
Putting his head down to avoid getting a direct blast from a sprinkler

Generally I'm pretty comfortable for anything under 30-40 miles on my road bike, but apparently due to an unusual amount of squirming as I tried to avoid the sprinklers, after a lap or so I wasn't and this was only a 25 mile ride.

The Park Service puts up a sign that notes that the river water is not potable - so we won't try to drink from the sprinklers, I guess. But is it suitable for showering?

Of course, if they feel that the grass on Hains Point needs to be green, I guess it makes sense to use the river water.

Best Bike Parking - for Some

Police Bike Parking
Four spots set aside for three police bikes

In my office building on Capitol Hill, we are protected by federal police. This parking lot has 24 slots for bicycle parking, half in the center and half at one end of the garage. Through some sort of unspoken tradition, the bicycle commuters know who parks where. This has been upset by the police taking four of the 12 spots near the center in order (at least for now) to park three bikes. (One of the bikes is made by "Smith & Wesson" - well known for making bikes! Stop or I'll shoot you with my bike!) This has completely upset the bicycle commuter ecology right in the middle of the prime riding season. (Well, ok with the heat wave, maybe not entirely prime in the usual sense.) So the police have three bikes on the four closest most convenient slots and the staff who are bike commuters have crammed ten, eleven, etc bikes into eight slots to see how much paint they can scrape off each others' bikes.

These police bikes are locked up with the most absurd chains and padlocks - you would think they were locking them up in some high crime area and not in a garage guarded like a fort.

PS - I thought perhaps this gift of parking places to the police might put us out of compliance with the DC "for every ten spots for cars, one for bikes" law but they count the slots on bike racks in front of the building. 95 percent of the car parking is in a garage and 75 percent of the bike parking is outdoors. Oh well.

Cyclist-Diplomat Endorses U.S. Tobacco (1917)

The connection to cycling is a bit tenuous, but Alvey Adee of the Department of State was known to take long cycling vacations in France, so here he is said to draw on that experience to endorse American tobacco for U.S. soldiers serving in France over the French (or European) product.

Diplomat & Cyclist & U.S. Tobacco
This seems to be an endorsement of a way that The Times supported the war effort (during World War I)

Alvey A. Adee Says Boys Need U. S. Tobacco

Alvey A. Adee, Second Assistant Secretary of State, is a diplomat. Mr. Adee is generally given credit for the unusually diplomatic language in which the United States couches its communications to foreign governments. Mr. Adee has been in France several times, riding through the beautiful roads of that country, on his bicycle. Mr. Adee knows the French tobacco. But -- Mr. Adee is a diplomat.

So here is is how he sums up the smoke situation for the boys in France:

Times Smoke Fund,
Washington, D. C.
My experience with foreign tobacco during my bicycle trips over what is now the Battlefield of Europe, makes me very sympathetic to your plans for furnishing our soldiers with the tobacco to which they are accustomed. It is a very splendid idea. Very cordially,
Alvey A. Adee

Police Ticketing Sunday Bikers, Haines Point


View Larger Map

Sunday morning at 9 am I took off to Haines Point in Washington DC to do some laps of the trianguler peninsula along the Potomac River. I have seen U.S. Park Police writing tickets at this same location, the junction of Buckeye Drive and Ohio Drive, before on a weekday afternoon but not on a weekend. Anyway, every time I went past on my laps, they had someone different (sometimes groups) stopped. I don't know if they were giving tickets or just warnings, but I suspect they were writing at least some tickets. It can be a $50 ticket if they write one. On my last time through, a bit after 10 am, there were two Park Police vehicles parked up on the median strip in plain sight and they were still pulling cyclists over.

Weight of Cycles (1890s' View)

Cycle Weight
A discussion of the all-important bicycle weight question

A prevalent notion regarding the weight of cycles seems to be that the lighter a machine is, the easier it must run. While for race tracks this is practically true, such conditions as are met with in average road riding alter the case considerably. Lightness is certainly a most desirable and important quality to secure in a cycle; but the moment it is obtained at the expense of rigidity, or at the expense of generous tires, it does not make the machine any better as a whole. Lack of rigidity means waste of power, and small tires mean more vibration; and both these are detrimental to ease of running, especially at any distance. Should lightness be further obtained at the expense of a well-stayed frame, or use of insufficient metal, durability is largely sacrificed. It does not follow from this that a machine need be heavy; for a properly proportioned one of medium weight and first-class quality is just as strong; but it does follow that extraordinarily light machines are not suitable for road work, and are not as durable as those of medium weight.
A reasonable point of view! The author goes on to offer further analysis~
Since 1892 the advance that has been made in building light bicycles has been absolutely extraordinary, and in less than three years the weight of road machines has been reduced from forty-five to twenty-two or twenty-three pounds. No man, however heavy, need ride a modern wheel of over thirty pounds' weight; very few need ride over twenty-five pound wheels, while the majority of good riders can be safely fitted with wheels that weigh but twenty-two or twenty-three pounds. Of course a good many wheels at even less weight than this will be used on the road, but it should be done with extreme caution. Track racers run from fifteen to eighteen pounds.
A modern carbon fiber racing bike that weighed around fifteen pounds would be a costly item, but the track bike described for the 1890s would not have any gears or brakes, which do add weight even on a modern bike. And to save weight, the wheels of an 1890s track bike might well have been made of wood.

Still, one wonders at how quickly steel cycle builders of the 19th century managed to make lightweight track cycles that rival those of a hundred years later in certain measures.

More Accurate Video of Dutch Cyclists

One of the blogs I follow was the source for a video that ended up having zillions of page views, apparently because so many outside of the Netherlands found its depiction of cycling so confounding, according to a recent post. I used it in a earlier post myself.

The speeded-up version of Dutch commuters that received so much attention

The speeded up version does reduce the "boredom factor" and makes it clear more quickly how many cyclists are moving to and fro in such a business-like way.

Now however the blogger has released a real-time version, which I think makes the same points just as nicely.



Real-time video of same intersection

At about 45 seconds, a father (presumably) takes off from a stop with his son on a bike to his right (and daughter riding in a seat and behind him), putting his hand on his back to help get him up to speed. Don't see much of that here.

The mix of bikes is interesting, too, and easier to observe at the slower speed. Bikes in the Netherlands are obviously more about urban transportation and (much)less about sport - I saw only one or two drop handle road bikes among all these. Of course, part of that may well be that cycles are required to have a headlight and tail light and most of these bikes, used daily, have fenders (with the tail light built into the rear fender).

I find it interesting how practically everyone seems to be following the rules (or laws, I suppose). There are the occasional riders who don't stop for the light, but they are very few. And of course the sheer volume, even in real-time, makes an impression compared to the Washington DC area. Even in real time, the left turns by some of the cyclists seem almost choreographed. Of course, the real-time version takes five minutes and the speeded-up version takes only two. . .

Rights of Cyclists on the Road (1895)

From page of Cycling for Health and Pleasure, published in 1895:

Rights of Cyclists on the Road. — The right of the cycle on the road is the same as that of other vehicles, — neither more nor less, — and is so held by the courts. Wheelmen have, in some places, been put to considerable labor and expense to establish this fact; but have done so with uniform success, chiefly through the efforts of the League. Of course, when the cycle makes its first appearance in new regions, the blind conservatism which seems to be inherent in human nature is apt to breed prejudice against it; but moderation and experience, with firm prosecution of any case of infringement of rights, will soon put things on a right basis.
Rights of Cyclists on the Road
The more things change, the more they stay the same

Keeping in mind that this was before there were cars on these "highways" mentioned, it goes on to say:
In many localities wheelmen have been accorded advantages much in excess of their rights. They have been granted the privilege of using side paths and even paved walks; no objection has been made to their coasting on crowded hills, and forcing other vehicles from their track; and they have been permitted to ride at racing speed, even on crowded highways. Such concessions have had the effect of making many wheelmen very careless of the rights of pedestrians, and of those of drivers of wagons and carriages, while asserting their own rights and privileges to the full. By so doing they have intensified the prejudice already existing in some quarters against the sport, and have aroused the prejudice of others whose rights have been infringed by being rudely driven from their path, or portion of the road, by the necessity of giving ample space to some reckless rider. It is not only bad form and worse manners to act in this way, but it is most wretched policy, for it injures the whole body of wheelmen in the eyes of the public.

Where roads are bad and wheelmen are permitted to use side paths, they ought to reciprocate the privilege accorded them by extending every possible courtesy to pedestrians, never warning them off the path by bell or whistle, but rather, by riding slowly and requesting the pedestrians to kindly allow their passage, and thanking them when they have done so. There are many cyclists who are thoughtless in these matters, and there are others who pretend to believe that it is pusillanimous to extend such courtesies ; but they ought to remember that they are on a path
only by courtesy, and are bound, in common decency, to return that courtesy.
In summary, cyclists have equal rights, but they should behave reasonably towards others. And if they have been accorded special rights, courtesy is to be expected.

An 1890s View On Safety

Title page
Title page of the popular 1890s book, "Cycling for Health and Pleasure

The view on crashes between two bikes would probably not meet with the approval of modern litigators. From page 67 of Cycling for Health and Pleasure, published in 1895:
Riders ought to observe all the rules of the road, and not court disaster or engender ill feeling by disregarding them. It is very common for a number of wheelmen to divide, both on meeting and passing vehicles, and in so doing increase the chance of frightening horses, and make collisions far more probable. In the case of collision between two bicycles, it should be remembered that the aggressor will receive the less damage if the machines are of equal strength, so that if a collision is actually unavoidable, it is worth while to become the aggressor if possible, or at least to endeavor to give as much shock as you receive.
"In case of collision between two bikes"

"Cycling for Health and Pleasure" was apparently popular - the Library of Congress has editions from 1890, 1895 and 1896. The 1890 version was published by the small "Wheelman Press" while the later editions were published by the large commercial publisher Mead, Dodd.

Wheels & Bikes at Shirlington

In front of Shirlington Library

So, why the locked up "extra" wheels at this bike rack? How did this happen? (These photos taken early Saturday morning before they are obscured by other parked bikes.)

100 yards/meters or so away, we have this sad Mongoose that has lost its wheels - perhaps they are locked in front of the library!
