"Speed Kills" - According to the Seattle Dept of Transportation

The Seattle Bike Blog has a recent post about e-bike versions of LimeBikes that is interesting to read. The description of the apparent success of dockless bikeshare in Seattle is intriguing since their attempt at "traditional" docked bikeshare was a failure, only getting to 500 bikes available before being shut down. And now they have dockless e-bikes too.

The blog post talks about how the LimeBike e-bikes only provide powered assist up to about 15 miles per hour. This is explained as follows: In part, this is for safety and liability concerns. As the Seattle Department of Transportation regularly reminds us, pedestrians have a one-in-ten chance of death when a driver collides with them at 20 mph. For LimeBike, any crash or collision at that speed is a serious liability.

I first read that (too quickly) as having to do with the speed of cyclists, not cars, and involving cyclist crashes - thus getting two aspects wrong. Oh well. There probably aren't good numbers about how the speed of a cyclist relates to crash outcomes, but it likely that the faster one is going, particularly beyond 20 mph area, the more likely the outcome will be more unpleasant (for the cyclist - and also for whoever he may run into who isn't in a metal box).

This is why I am often unhappy with the so-far relatively few e-bike equipped bicycle commuters I see whose main goal seems to be to emulate car-like average transportation speeds on their overall commute, chugging along the Mt Vernon trail along the Potomac at between 20 and 25 miles an hour (and beyond). Counter-intuitively many such riders are highly disinclined to slow down when presented with traffic or to exercise what would seem like common sense, instead passing at the highest speed manageable with little apparent interest in anyone's safety. (Of course, this is not true of all e-bike commuters, some are a little more safety minded, thankfully.)

The speed limit for cyclists on the Mt Vernon trail (as one example) whether riding an e-bike or a regular one is 15 mph, so someone traveling at 22-24+ mph is traveling well in excess of the speed limit. Now if there is a fantastic tailwind (which is very rare with the direction of my commute) I may average 20 mph for a while but 16-18 is more typical as my high speed - also exceeding the speed limit, but only by ten percent or so, and not exceeding the 20 mph "death zone" speed.

It is also relevant that the trails are used by persons on foot, running or walking, and that the trails around here are typically not very wide or all that well maintained. The mix of 3 mph walkers and 23 mph e-bikers on these trails is not good for anyone.

The Invisible Mile by David Conventry (Book Review)

The Invisible Mile: A Novel by David Coventry

My rating: 3 of 5 stars


I am something of a cycling enthusiast, although my interest in modern professional road racing has mostly collapsed, I guess from fatigue with doping scandals.

There are some topics that are, let's say, overworked. For U.S. history, topics such as the Civil War, for example, or something about Abraham Lincoln. For books about cycling, the Tour de France has somewhat the same place - it feels like every third or fourth book involves the Tour somehow. This is a work of fiction drawing on actual events at a particular Tour, the 1928 version. At that Tour there was a mostly Australian team; the main character of the book is a fictional participant from New Zealand. The rest of his team are historical figures from that race, as well as other named riders and a few race officials and others.

The structure of the Tour de France has evolved (and perhaps also devolved) over the years - I should have read the Wikpedia entry on the Tour de France for this period before reading the book for some basic context.

The book has several plot lines - one is certainly the main character's participation in the race, and much about the race itself with particular focus on its many grueling aspects. There is at least one other plot line, although perhaps it's more like several others, and I somehow never engaged will with any of that.

I didn't read the book properly, I guess. Oh well. I enjoyed the cycling parts.

Bicycles on DC Streets 1907 (Compared to 1903)

Washington, D.C. clip of Pennsylvania Avenue in 1907 from GhostOfDC

In two different earlier blog posts, first this one and then this one I looked at bicycles that appeared in two short videos of DC streets in the summer of 1903. I have now found the above video of Pennsylvania Avenue in DC, with the U.S. Capitol in the background, from 1907. One can see a lot of change in the four years!!


At about 25 seconds in, a cyclist first appears riding from right to left

The main impression of change is WOW there are a lot more cars carrying passengers on a main thoroughfare in Washington DC in 1907 than there were in 1903, and far fewer horse-drawn carriages. The fellow with a hat facing the Capitol is apparently a traffic policeman who casually directs traffic and to some limited extent, pedestrians.


This is the same cyclists as above, having made a left turn in the intersection and now proceeding away from the Capitol

The cyclist proceeds as any other vehicle, motorized or horse-drawn, riding in the main part of the street.


Another cyclist appears

There are some small breaks in the film - it isn't clear how this cyclist got to the middle of this intersection, but probably he was riding away from the camera and towards the Capitol, then stops or slows to turn to the left.


Because of heavy traffic, the cyclist starts to ride away from the Capitol but then turns to his right

The cyclist makes his left turn in two stages - first, he makes a U-turn, then once he is established heading in the reverse direction and traffic clears to his right, he makes a right turn to complete his original left turn. The traffic policeman plays no role in this maneuver. Note that cyclists in this intersection would have had to navigate safely tram rail tracks in two directions, crossing those at as close to a 90 degree angle as possible.


One of several vehicles spewing vast amounts of exhaust, which can't have been too pleasant


One of only five horse-drawn carriages in the short video

Cars carrying passengers have skyrocketed and horse-drawn carriages, all appearing commercial in nature, have dropped off in number from 1903 to 1907. There are still many streetcars in this urban setting. And there are still bicycles, but the ease with which they can be navigated is much changed for the worse, which probably meant fewer were riding as shown here (although these short videos are of course a very small sample).

More Bicycles on DC Streets 1903

In an earlier blog post I looked at a short film available as a video via the Internet meant to show US Post Office operations from 1903 in Washington, DC. I found another.


The version on YouTube is so poorly rendered as to be almost useless

The default viewing version is poorly rendered here but the downloadable mp4 file is acceptable.

In this film, meant to show Post Office operations, you can see a certain amount street traffic as well. (The video is apparently meant to show how bags of mail are transferred between a street car and a Post Office horse-drawn wagon.) There is less than a minute and half shown of a major street in Washington DC. Whatever time of day this was, filmed in July 30 1903 (a Thursday), there wasn't much traffic generally, however I am struck by the number of bicycles. It isn't a vast number, but they are clearly being used for transportation by adults.


Cyclist appears suddenly at left, proceeds at measured pace out of view


Next cyclist appears at right, again riding at a measured pace


Due to low resolution, it isn't obvious but a cyclist is proceeding right to left on the next cross street in the distance and is just visible in the space been the streetcar and the Post Office wagon.


Cyclist rides into view, apparently against the flow of traffic on this side of the street

Street mail car, U.S.P.O.
Summary-The first scene appears to have been taken on a main thoroughfare of large city. In the immediate foreground is a horse-drawn U.S. mail vehicle waiting at the side of a streetcar track. Soon a streetcar approaches the camera position. It stops beside the mail vehicle and the driver unloads mail sacks from the streetcar. He then puts some sacks from his wagon onto the streetcar. As the film ends, both the streetcar and the horse-drawn mail delivery wagon leave the scene.

The Cost of Cycling for the "Modern Athletic Girl" of 1896

WHAT THE "MODERN ATHLETIC GIRL COSTS. The Various Items of the Necessary Summer Sporting Outfit. From The Journal newspaper (New York), Sunday June 26, 1896 (https://www.loc.gov/resource/sn84031792/1896-06-28/ed-1/.

The Journal newspaper of 1896 in New York carried far more pages than other urban newspapers in the U.S. at the time and worked hard to fill the pages up with various kinds of human interest material. 1896 was the height of the so-called "bicycle craze" in the U.S. so here we have an article that combines that topic with women and sports. Probably because of the exceptional popularity of bicycling at the time, it is discussed first, then golf, hunting, and other sporting endeavors. Cycling is also given here as the most expensive at almost $200.

The father of an up-to-date society girl who decided to take up athletics this Summer consented with pleasure to buy his daughter a $100 wheel, thinking that $125 at the highest would be all the money necessary for him to spend on her bicycle outfit. The following Is an' Itemized account of the bills which were sent him for everything pertaining to her bicycle outfit: Bicycle, $100; lamp, $5; cyclometer, $1.25; bell, 50 cents; foot pump, $1.50; bicycle stand, $2.50; lock, 50 cents; silver name plate, $2; knee protector, $3.50; Summer bicycle costume, made to order of linen homespun, $25; linen knickerbockers, $5; one pair low bicycle shoes, $4; one pair boots, $6; three pairs of silk stockings, $G; three pairs golf stockings, $6; linen hat to match suit, $3; six shirt waists, $18; pair of gloves, $1.35, making a total of $191.10.

Arguably the amount and cost of the "required" clothing is intentionally varied and high in order to support the article's point that such activities are expensive; it is more interesting to see what are given as typical accessories, including lamp, cyclometer (measuring distance covered), bell, footpump, stand, and lock. (I wonder how the lock would have worked - in looking at ads and articles about cycling at the time, I have not commonly observed a lock set-up for bicycles.)

Descent: My Epic Fall from Cycling Superstardom to Doping Dead End (Book Review)

From Flickr, user Vanil-Noir

Apparently there is a sub-category now of cycling literature, the "I was a great bicycle racer, but then somehow I became a doper and it all went to hell" tell-all, as-told-to-someone-who-can-write memoir. We have Tyler Hamilton's "The Secret Race: Inside the Hidden World of the Tour de France: Doping, Cover-ups, and Winning at All Costs" (2012) and then there is David Millar's "Racing Through the Dark" (2011). Mr. Dekker is a little late to this activity, since all three are reporting on much the same period of doping, but Dekker attempted to continue his career later than the other two so only got around to publishing this late in 2016 (in Dutch; the English version was published in the US about a year later).

As a highly successful Dutch bike racer in a land of cyclists, Dekker was presumably as much of a name there as Lance Armstrong had become here. In Dutch, the title of his book was "mijn gevecht" which apparently translates to "My Fight" (or maybe "My Struggle"?). With himself, I guess.

I thought that to be clever they used "descent" as the title in the English version since cyclists who win typically have to be good at descending mountains as well as racing up them, to give the title kind of a double meaning, but in reading it I eventually decided that was just coincidence. The cover of the Dutch version has Dekker in 3/4 profile, looking as come-hither as a sanctioned cyclist-doper can for his Dutch admirers. It's a little . . . odd.

I gave this two stars because . . . well, I didn't really like this book. It was pretty depressing, in fact. The main plus is that it is just over 200 pages with fairly large print - it is a fast read.

Tyler Hamilton's book was not so heavily focused on doping, he talked a lot about racing. The discussion of doping was mostly amusing since it became clear that he ran into problems largely because the team he was on after being with Lance Armstrong didn't spend the kind of resources organizing doping and that Hamilton realized eventually that poorly organized doping is not a good idea once he accidentally ends up with someone else's blood transfused into his system instead of his own. Oops! David Millar's book is hideous because it talks way too much about David Millar - but even he has more blow-by-blow description of races he was in than this book. "My epic fall from cycling superstardom to doping dead end" means you read far more about doping as well as drugging and drinking and sleeping with hundreds (his word) of women than about any races he was in. One wonders why VeloPress thought it was publishing a book about cycling. There are endless examples of how he wasted money, giving Euro values in most cases - 25,000 Euro for this evening, etc. Ugh. Simply ugh. (The apparent need to list his Euro salaries for all the different years he worked is just plain weird. I half expected him to say how much he got for writing this book.) And there is certainly far more detail about the mechanics of doping as he practiced it, and a fair amount of description of how members, managers, and others of his now defunct Rabobank cycling team supported his and others' doping.

I read to the end - now not sure why. Does he make some statement or apology at the end that redeems himself at the end? Spoiler alert that probably isn't a surprise - no, he doesn't.

I might have felt better about investing the time to read this if I had come away with some understanding (or feeling of understanding) of why someone would do this, why he did this. This is almost entirely missing, other than that it was the culture of the team and (in effect) "everyone did it" (although he does mention at least one other rider who didn't, but who only had moderate results). He describes the trip down but makes no attempt to explain what we might be able to learn from this from his perspective.

Bicycles on DC Streets 1903

"Collecting mail, U.S. Post Office"-digitized short film shows a few bikes in street traffic

This short movie from the collections of the Library of Congress shows two post office boxes on a street corner and was apparently intended to show how the Post Office employees serviced them. Separately the video shows something of what street traffic was like, including persons on bicycles, which from my perspective is far more interesting. (The video is not identified with any tags or other access points suggesting cyclists are part of this. Typical.)


First cyclist enters screen from left at around 15 seconds, riding parallel to a streetcar

The first bicycle rider shown looks to be an adult man riding at a moderate pace, likely to get from one place to another - bicycle as transportation that is faster than walking and less elaborate than using a horse-drawn carriage.


At about 20 seconds, second cyclist appears in upper middle of screen as traffic clears, riding across intersection from cross street

Much like the first bicycle rider, bicycle as transportation. I was amused by the man walking across the street in another direction, who ambles rather casually.


At 28 seconds, third cyclist appears from left, who has a boy sitting on the handlebars as a passenger

All the cyclists shown are traveling at a moderate pace. If you look closely, you can see the rider here pedaling steadily. It is almost certainly a single-speed bike.


At 32 seconds, fourth and last cyclist appears from right, cutting through the intersection

A little hard to tell, but this appears to be a younger rider, moving at a faster (but not that much) pace. He seems to ride in front of two women who are going to cross the street. He has a bag of some kind in his hand held to the handlebars.


No bicycle shown here, but you can see four different horse-drawn carriages at once near this Washington DC intersection in 1903

Most of the "traffic" shown during the video consists of horse-drawn carriages. Two different streetcars pass, one in either direction. There are a moderate number of pedestrians, and then the four cyclists, one with passenger. All the traffic is moving at a moderate pace - the horse-drawn carriages in particular. Most of the pedestrians are shown walking briskly and enter the intersection without pause - one suspects that absent many cars, concern about entering intersections was much more casual.

One assumes that this was shot during the middle of the day and that the various traffic elements are representative. The use of bicycles looks pretty high. Interesting.
