My BikeDC 2011 Experience

The last time I rode in BikeDC was in September 2001 - the George Washington Parkway portion was removed that year because it was something like ten days after September 11 and they could get the police support required (or something). I'm not a person who likes crowds but I have had this interest in riding on the GW Parkway so once it was clear that the weather would be OK this year (for a change - last year was a downpour) I signed up.

The event has a more or less rolling start - I got there (having ridden in on my bike from home) about 15 minutes are the first riders hit the course from just west of the (U.S.) Capitol, riding off through closed (to cars) streets in downtown DC, crossing the Roosevelt bridge into Virginia and heading north(ish) on the George Washington Parkway and heading a few miles down the Parkway before turning around and heading back up the Parkway, then the official route crossed back into DC for the finish (but I just road home).

Sparse (relatively speaking) bike travel in downtown

Starting 20-25 minutes after the initial bunch seemed to work out well at this point - not too much (bike) traffic.

Not long before the Roosevelt Bridge, we rode through a short tunnel

After crossing the Roosevelt Bridge and approaching the GW Parkway, the bikes bunched up more.

Here you get a sense of the mix of riders - there are some spandex "we could go a lot faster types" but the crew on the tandem are just rolling along and then there are kids, too.

Nearing the GW Parkway

Beyond the Key Bridge the bike traffic became quite heavy - the bikes only had one side (two lines) of the divided highway, with bike traffic in each direction confined to one lane (with cones down the middle). Round about now I began to wish for more common sense and more common courtesy from my fellow riders. As we climbed, relatively slow moving (bicycle) traffic filled the entire single outbound lane. Some people riding uphill nonetheless impatiently tried "on the left" when what they meant was, "you're in my way; I want to go faster." Some crossed over into the oncoming lane (for bikes - usually a lane of traffic in the same direction) to pass the entire column, then pull in with the other riders (who would more or less have to let him or her in).

Some riders barreling down the GW Parkway on the return side presented a more intimidating picture - here there were some people whose cries of "on your LEFT" really sounded like "OUTTA MY WAY or I may run into you."

Now this sounds like chaos, but probably it was one in 250 or less that was acting in this way, but when you have thousands of riders on a few miles of road, 1-in-250 makes an impression.

Fortunately all the bike crashing I saw was small-time stuff and no one was significantly injured. I observed several obviously (or one assumes) really new riders fall for no particular reason and on the Parkway, fortunately while moving only a few miles per hour, a bike turned into another causing a tangle of metal and rubber.

Nearing the turn around to head back on the GW Parkway

Last but not least - the one guy I saw who wasn't wearing a helmet, wearing a WABA jersey.

Yeah, image is a bit out of of focus, so his head looks funny - but there isn't a helmet on that head is what you can see readily enough. I don't believe wearing a helmet was required, but still.

The ride continued southbound on the GW Parkway and was, I thought, supposed to continue to the Air Force Monument, but at the Arlington Bridge there was some sort of accident (involving a cyclist? not clear at the time, or now for that matter) that had many emergency vehicles and a medevac helicopter. About a quarter mile beyond that was a turn around again on the GW Parkway to circle back and return into DC. Having had enough of a BikeDC experience for one day, I moved over to the GW bike trail and rode the eight or so miles home.

I guess overall I had an enjoyable experience, but I can't say I feel much of an urge to do it again at the moment, either.

Bike to Work Day, 2011, Arlington VA

Inadvertantly part of a "new rider convoy" near National Airport on the GW Parkway bike path

Since I pretty much bike to work every day, I am never quite sure what to think of Bike to Work Day - at least this year the weather was mostly good (in the afternoon it clouded up and at least a few drops of rain fell some places). The number of riders for this "event" looked pretty impressive, but the fair weather aspect of this is fairly apparent when compared to earlier in the week when it had been rainy.

In the photograph the barbed wire is more noticable - normally I am looking forward I guess and don't even see it.

As riders get into the District, the group disperses

I tried to take some other group photos of "convoys" but my camera had focus issues. Oh well, maybe next year!

Book Review - "It's All About the Bike"

"It's All About the Bike: The Pursuit of Happiness on Two Wheels" by Robert Penn. Published April 26th 2011 by Bloomsbury USA, 208 pages.

Book description at Goodreads.com.

YouTube video giving author's description of his book

Here's my review on Goodreads ~

The author describes some of the history, particularly the early history, of the development of cycling along with an account of his selection of the bits and pieces that are eventually assembled to make his dream bike including visits to manufacturers, all in less than 200 pages. Since I have a coffee table book that describes the history of just derailleurs, in my view he summarizes, generalizes, and leaves some (OK, a lot of) stuff out. For me, knowing something about the subject, it was an interesting read - I enjoyed it. I have to wonder how a reader who was interested in bikes but didn't know that much about the subject would find his explanations of certain slightly technical subjects. It would have been great to have more and better illustrations.

I read the U.S. edition. The dust cover of the U.K. edition included a color photo of this bike he went to so much trouble to have built; it seems odd to have left that off the dust cover of the American version. The British English was not fixed for the U.S. edition - I thought that was a standard process. "Tyre" etc. Not a big deal but seems odd. U.S. distances are supplied in addition to kilometers etc.

Even having read his book, I still don't quite understand what this was the ideal bike for (given that he has six other bikes of various types). It almost seemed like he wanted a randoneering (touring) bike, anyway something for long-long rides, but the subject of randoneering (with its rather different views of many of the choices he made) doesn't come up.

At the end he points out that the bike cost him $5,500. (He translated that to a U.S. measure, anyway). There are plenty of off-the-shelf bikes that cost more than that, so I think he must have got some special pricing on some of it. (Which is fine.)

I have a few other thoughts since I wrote the above ~

* Coming from the U.K., he really has a very European focus in the components he finds interesting. This isn't really a problem per se, but it would have been nice if he could have said a little more about some of the other sources that are important today. Yes, Campagnolo of Italy has made and continues to make great components, but they are mighty pricey and most people are making other choices - Shimano and increasingly SRAM.

* I still don't really understand his "dream bike" except that it is a really sturdy road bike made of steel. He says he figures he'll still be riding it when he is 70 down to the pub, but I am doubtful he'll want to ride what is essentially a racing bike to the pub then. He says nothing about randoneering bikes that seem a lot more "dream bike" to me, but perhaps this movement hasn't caught on in the U.K. (I don't think this fellow reads Bicycle Quarterly, the mother-ship journal of rando cycling.)

* With all the choices in the universe, he has his custom bike painted orange and blue - really, orange and blue? The Denver Broncos. Oh well.

* I also didn't get his choice of carbon fiber Cinelli handlebars for his steel bike, particularly since as I read the book, he got Cinelli Ram bars that integrate the stem and the bars, but on his site the photo shows carbon fiber handlebars with a standard stem. The photos of Cinelli Ram bars that I have seen are quite exotic - so much so that they would grab much of the attention on any bike you had them. Anyway, I must have misunderstood something, but I would have chosen something more traditional for the handlebars.

* The book is mostly about his quest for a perfect road bike of his own profile, but he does meet Joe Breeze of mountain biking fame and describes a pretty amusing outing with him, riding down a famous old mountain track. A lot of his descriptions of discussions with the people he meets who create (or whose companies create) the parts of his bike are engaging; really, that stuff is better than some of his descriptions of early cycling history.

National Jukebox - 1901 Recording About Bicycling

Uncle Josh Weathersby on a bicycle, performed by Cal Stewart, January 8, 1901 - a two minute, 41 second recording from a 78 record of a then-humorist spoofing cycling. Part of the Library of Congress' new "National Jukebox" that streams audio recordings from the late 19th and early 20th century. There are a fair number of "spoken word" performances and not just music.

Quadricycle Fire Engine (1896)

Article in the April 25, 1896 issue of Scientific American.

Figure 1 - Quadricycle Fire Engine

A QUADRICYCLE FIRE ENGINE

We illustrate herewith a quadricycle fire engine that attracted considerable attention at the recent bicycle exhibition at Paris, and which presents unquestionable advantages over the hand engines in use in all places that are too small to afford the luxury of steam fire apparatus.

As shown by our engravings (Figs. 1 and 2), the engine consists of two tandem bicycles coupled by crosspieces in front and behind and having but a single steering post in front. The free space between the two frames is occupied at the front by a hose reel, in the center by a rotary pump, and at the back by a coupling that allows the pump to be put in communication with a water tap.

This entire affair weighs scarcely more than 180 or 188 pounds, which represents about 88 pounds per man. [This per man figure does not seem right, whether the riders' weight is factored in or not, but is what is stated in the original.] It will be seen that upon such a machine four trained cyclists can reach a fire at a speed that could never be attained by fire engines drawn by horses.

Figure 2 - Ready for Operations

As soon as the engine has reached a favorable position, the four men jump from their seats, and, while two of them adjust the couplings, a third unreels the hose, and the fourth, turning down the jointed support, raises the back of the machine and throws the pump into gear.

The four men afterward get into their saddles and pedal in situ with a mean velocity that causes the pump to discharge about 4,500 gallons an hour in the form of a stream 100 feet in length in a horizontal direction and about 75 feet upwardly. These figures are those obtained at the trials made at the Palace of Industry on the 23d of last December.

All the preparatory maneuvers require scarcely more than two or three minutes. If, on another hand, we take into consideration the fact that such machines, propelled by men with some little training, can reach a fire in a quarter or a third of the time made by ordinary hand engines, we shall realize how great an interest attaches to the use of them in country places where a fire so easily assumes the importance of a disaster by reason of the tardiness with which the first help comes. Everything, therefore, leads to the belief that this invention is destined to completely revolutionize the fire apparatus of small towns and villages.

An interesting notion - I don't believe this caught on in the U.S. In a radius of travel less than a couple of miles and with relatively flat terrain, this could make sense, but notwithstanding the advantages of quick response cited, one can imagine fire fighting personnel would prefer not to pedal to fires.

Advertisement for the Side-by-Side Tandem (1896)

In an earlier post I described and presented information about the Punnett Tandem Bicycle as described in the September 4, 1896 Scientific American - in the same issue at the back is an ad for this bicycle.

Forty pounds in weight and only $150!

While it is supposed to be reasonably easy to mount this thing, one can't help noticing that both gentlemen mentioned in the ad are noted for trick riding.

Black Bicycle Mfg. Co. - 1896 Bicycle Factory

The Black Bicycle Mfg. Co. in 1896, external view

The January 4 1896 issue of Scientific American has illustrations showing scenes from the Black Bicycle Manufacturing Company factory and some description of the manufacturing process in an accompanying article.

THE TRIBUNE BICYCLE

Within the past three years, the American bicycle Industry has grown up to dimensions which fairly entitle it to be considered representative of the country and of the day. Every day sees hundreds of wheels of high and low grade made in the factories of this country for the American and foreign market. Three years ago the English bicycle was considered by many the best wheel, and the possessor of such was apt to consider himself better equipped than his friend who rode one of American manufacture. Now, all is changed. A visitor to England or to the Continent, if a cycling enthusiast, cannot fail to be impressed by the superiority of American wheels as contrasted with the foreign ones, and no wheelman really an fait in his subject would dream of buying his wheel abroad, so superior is the American make. The industry has brought about an enormous development in the manufacture of special tools and of parts of bicycles.

Assembling the Bicycles

Many assumed bicycle manufacturers simply buy these parts and do their own assembling. But for the production of the absolutely high grade American bicycle, a factory is required which will turn out practically all the parts of the wheel manufactured, for unless such is done one concern cannot be answerable for the perfection of the whole machine.

We select as the representative of such a factory the works of the Black Manufacturing Company, of Erie, Pa., a company which produce the highest grade of wheel and which put it on the market purely on its merits without the adventitious advertisement of paid riders. The wheel made by this company, the "Tribune Bicycle," embodies the best possible practice and is correspondingly free from structural variations of unproved merit.

Milling Machine

The tubing, whose walls are of 20 gage thickness, is of American make, the company having found that English tubing could not be obtained of sufficiently even quality. At the junctions of the tubes forged connections are employed. These are received in a solid state and are machined out, drilled and turned, until only a shell of the original material is left. Each connection has projecting nipples which enter the ends of the tubes, and the whole is so accurately made that when the ends of the tubes are placed over the nipples the frame will hold itself together without further fastening. The tubes are of uniform diameter throughout and are simply cut of proper length, so that their natural strength is unaffected. The most striking instance of the preparation of the forged connections is in the crank bracket. This is received as a massive forging weighing 3 pounds 2 1/2 ounces, in general shape a cylinder, with four solid projections. This is put into the finishing machine and finished. It comes out with the solid cylinder drilled out so as to present a large aperture through which the crank shaft is to go. and its ends faced off and finished for the reception of the ball races: The four projecting nipples are drilled out and are also turned down on the outside so as to fit accurately the outside of the tubing. The bracket now weighs 8 ounces; all the rest has been converted into drill chips. One of the typical connections is that used for the head of the rear forks, which forging we specially illustrate, in order to show how solid a construction is given to this vital point.

Rear Fork

The frame has now to he brazed together. The pieces are placed in a massive iron jig or template, adapted to receive them and retain them in position, and which holds horizontally the entire frame. This template is mathematically accurate. While held therein, holes are drilled through the connections and tube ends and pins are driven in, pinning all the parts together. When removed from the jig the frame is perfectly rigid. It now goes to the braziers, who, with the best quality of brass and with large gas blowpipes, braze all the the liquid spelter penetrating all the join even running out around the pins. The frame next goes to the filers, after the borax has been brushed off it, who with file and emery paper, go over all the connections and over the tubing, polishing it all, and removing every excrescence, which, it will be observed, gives the frame an absolute hand finish over all its surface.

Brazing Room

The forks taper toward the end, and to produce this taper cold swedging is employed. The swedging machine carries a heavy head like a lathe head or chuck, which rotates in a horizontal axis, and within which are eight hammers, which by the action of the machine move in and out in radial directions. A piece of cold tubing pushed into the machine and fed up by hand is subjected to a multiplicity of blows and has its diameter rapidly reduced, the workman being able to give it any desired taper. The metal thus tapered is flattened and bent to the proper curve to give one side of the fork.

Cold Swaging Machine
[For someone who doesn't know what "swaging" is - like me - you can read something about it in Wikipedia.]

The cups and cones for the ball bearings are made on automatic turret lathes, the turret carrying in some cases as many as five tools. A bar of tool steel which may be 20 feet long is introduced into the machine and is gradually and automatically fed up to the tools, which shape and cut off from it bearing after bearing, which drop from it every few seconds without any attention from the workman. A liberal supply of oil is kept in constant circulation through the machine, falling upon the cutting tools. The bearings thus finished are purposely left 0 005 of an inch too large. They are then screwed on a mandrel in a special lathe and the final finish is given by hand. They are then tempered by secret process with sperm oil and polished, coming out with a beautiful straw color, equal in finish to any steel tools made. The standard finish of the machine is black enamel and nickel plate. The enamel is put on in four coats, two of India rubber enamel and two polishing coats, the frame being rubbed down with rottenstone between the applications. This gives a finish equal to a piano body. To secure evenness the enamel is applied by dipping in a tank of the compound, after which the parts are hung up and allowed to drip to remove the surplus before baking. All nickel plated parts are first copper plated. This prevents water or moisture from getting under the nickel and rusting the steel and thereby causing a separation of the coating.

[Factory Floor]

The aim of the constructor of this typical American wheel has been to secure simplicity and produce an absolutely standard article. Its criterion is its quality pure and simple. There are, however, some novelties introduced that are especially worthy of illustration. One of these affects the crank and crank shaft mechanism, the crank being secured to the shaft in a new way. V-shaped teeth are formed upon the crank shaft and upon the aperture in the pedal arm. This aperture in the pedal arm is split and provided with a tightening screw. To attach the ciank arm to the shaft, it is thrust over the end of the shaft and the tightening screw is turned up, when it is secured as rigidly as if all were one piece of metal. Those who have struggled with the old-fashioned cotter will realize the advantage of this crank, which is instantly released with two or three turns of a screw.

The handle bar is made adjustable by an arrangement of equal simplicity and efficiency. The socket in the head which receives it is threaded. On the center of the handle bar is brazed a sleeve threaded with the same pitch of screw. The socket is split and provided with a tightening screw. The screw is loosened, the handle bar thrust through the socket and screwed into place. When at the desired angle the screw is tightened and the whole becomes practically one piece of metal. By reversing the handle bars, they can be used in up-tumed or downturned position.

The sprocket wheels ought not to be spoken of as a novelty now. They are cut to the cycloidal or theoretically correct curve, which avoids all friction of the chain against the teeth. This has long been the specialty of the Black Manufacturing Company, but now the system has spread among other companies, and cycloidal sprockets are characteristic of several other first-class wheels.

Cycloidal Sprocket

We also illustrate the system of truing up the wheel. Each wheel is mounted on a gaging frame, and the workman, by setting up and loosening the nipples, brings the rim into an absolutely perfect plane. The steering arrangement of the tandem machine deserves attention. Sprockets are carried by the front and rear steering posts, and these sprockets are connected by chains and rods so as to insure unity of steering action between the front and rear handle bars.

What I have done here is bring together the illustrations that were on the cover of the issue and with the article with my hand-corrected version of the OCR'ed text, but some errors likely remain (alas) - if you come across a mistake, let me know in the comments and I'll fix. Thanks!!
