Official Handbook [of 1890] of the League of American Wheelmen



Official hand-book / League of American Wheelmen
Published in New York City in 1890. From the collections of the Library of Congress.

Explanation of the contents on the title page:
COMPLETE LIST OF LOCAL CONSULS, LEAGUE HOTELS AND RATES, AND REPAIR SHOPS IN THE UNITED STATES; THE POLICY OF THE NATIONAL GOVERNMENT FOR 1890; SYNOPSIS OF STATE LAWS REGARDING WHEELMEN; THE L. A. W. CONSTITUTION AND BY-LAWS; RACING RECORDS, REGISTER OF BICYCLE CLUBS IN THE COUNTRY, NAMES OF OFFICERS AND NUMBER OF MEMBERS; ARTICLES ON THE ROAD QUESTION; TOURING, ETC.

In my previous blog post I linked to a book "Tourists' Manual and Book of Information of Value to all Bicyclers" published in 1892, two years after this time. The illustrations of the two books show the evolution during this brief period so that by 1892 a "safety bicycle" already looked much like a modern bicycle, as opposed to the safety bicycles of 1890, which look a little odd or strange by comparison.


Bicycle design is still evolving towards what we would recognize as "modern" in 1890

Smooth 26 Inch Tires for Zippy Ride

When I bought this bike, it had some Kenda knobby tires that are 1.95 inches wide (according to the sidewall) installed. Ths rims of this bike are a little narrower than the wheels on newer mountain bikes I have and the 1.95 tires looked a little odd on the more narrow rims. Also, they are noisy when riding, even when pumped up, and likely do little to make the bike zippy.

I found these Michelin Runn'r tires at Bike Tires Direct. There are supposedly made of the same rubber compound as road bike tires (although lots more of it) and yet only cost around 16 dollars each. The sidewall says that the max inflation is 87 psi, but at 75 they seemed plenty hard enough. Bike rides great with these.

Evolution of My Bike Helmets & MIPS

The Bicycle Helmet Safety Institute (aka helmet.org) says that Bell, for example, recommends replacing a bicycle helmet every three years - I think I've seen that elsewhere. Yes, what a wonderful world it would be for companies that make helmets if everyone followed that - but otherwise it makes little sense if the technology doesn't change.

In the late 1990s, I had a Specialized helmet that was mostly good for me since it was sized as a large (not "one size fits all") and I have big head. It was simply a chunk of Styrofoam (tm) with a blue plastic cover held in place with tape around the edge of it, some holes for ventilation, and simple straps. Space between head and helmet was provided by bits of spongy padding. It was good to put stickers on (the outside) but I think I outgrew that somewhere in my 50s.

In 2007 I bought a road bike that I guess was a ramping up in my seriousness (or something) so I decided I needed a new helmet - I found the red one made by Tirreno (which it seems is a Performance Bike house brand) in a large size on sale. It has been what I have used since. It looked sporty but I didn't find it terribly easy to adjust the straps, and recently the plastic ring that grips the wearer's head broke. The ventilation slots, while numerous, are narrower than the older helmet, which isn't so good. I also eventually realized it has a design flaw - towards the front there are slots that come together resulting in a parts of the helmet facing forward that could hook something hanging down from a tree (or whatever). This is in fact amazingly stupid (from a design perspective). Yeah, it is highly unlikely, but still - completely avoidable.

I have read about the MIPS helmet technology that is supposed to help prevent concussions by allowing the head to roll more easily in the helmet. Some people think this is baloney and maybe it is, but at least it represents an attempt at an advancement beyond basis protect for your head from a chunk of Styrofoam (TM). All the MIPS helmets are more expensive but I was able to find a LaZer Tonic (which apparently is intended for commuters) with MIPS from Bike Tires Direct for $75 on sale. It doesn't look like a road racing helmet (oh well) but it has good large ventilation holes, fits me well, and it is supposedly safer (maybe). I've ridden a few times with it; it seems good.

Raleigh Sports, Paris Variation of Braking

Raleigh Sports Paris-style
Raleigh Sports bike from 40 or so years ago, much like one I have at home

I have a very similar bike from what must be about the same time period. This one, parked on the streets for many years (one assumes) is in remarkably good condition - much better than the one I have (which I got only a few years ago from someone giving it away). It has some superficial differences - the rear rack that clearly came with it, for example, and the full rather than partial chain guard. But it also has a very surprising (to me) difference - the brake system is not a cable-pull system with caliper braking front and back but rather front and back rod-driven brakes that bring brake pads up against the inside of the rim. Just as a traditional caliper brake uses the rim like the disk of a disk brake system, this is like an open drum brake using the entire rim as the drum, but only pressing on one side. I don't even know what this is called. I am quite doubtful as to how efficient it might be.

Sunday Ride Along the Seine (March 20)

On Sundays in Paris various streets and roads are closed to vehicular traffic, including a stretch along the Seine river.

My wife and I were in Paris for a week in March. The weather was seasonal - so it wasn't too warm, but not cold, either. We didn't have any rain until the day we left. We were right in the middle of the city. One of the lovely things about Paris is that you can rent a Velib bikeshare bike for almost nothing for a week - 8 euros. Yes, 8 euros for an entire seven days! This can be done easily online in advance, and you get an account number and a pin number (which you have to keep track of). It is very nice to have available as a travel option.

These are the best not-very-good bikes in the world!

I didn't take photos with very many people in them, for some reason, but I thought for a cool cloudy Sunday that there were a fair number of people out, on bike, skates, hoverboards (a hoverboard training class), skateboards, and of course walking.
