So You Wanna Have The Lightest Bike On The Block...

So...You missed your opportunity to ride Gunter Mai's 2.96 kilogram Lightbike.  You hadn't heard about it. Or you did,  but couldn't find his website.  Or you did, but can't read German.  Or you couldn't afford it. (I didn't ask.  You know what they say:  If you have to ask, you can't afford it.)  Or you had some other commitment.

Well, don't feel bad.  You didn't miss your opportunity to ride the world's lightest bike after all. As we speak, a new, revolutionary velocipedic machine is being made from the lightest material known to humankind.

 

How light is it?   Try 100 times lighter than Styrofoam (you know, that stuff in your helmet).  And it's stronger than carbon-fiber, beryllium or any other metal that's every been used to make a bike or part on which you've spent your hard-earned money.

What is that wonder metal?, you ask.  It's a nickel-phosphorus alloy.  Even more important, though, it's drawn into tubes one-hundreth the breadth of a human hair and woven into a latticework that can withstand enormous stresses.

No one has said when a bike made from this material will be ready to ride, but here is a prototype.

Bicycles And The Eiffel Tower

On this date in 1889, the Eiffel Tower opened to the public.

Probably no other manmade structure in the world has served as a backdrop for as many bicycles and cyclists as that most iconic of buildings.  Made to serve as the entrance of that year's Exposition, it was, ironically, slated to be torn down once the fair ended.  And many criticis couldn't wait:  They complained that it interrupted the Paris skyline.



There are a number of reasons why la Tour and two wheels are so linked in people's imaginations.  One, of course, is that cycling, almost from its very beginnings, has been a seemingly inextricable part of French culture.  Another is that the tower is so associated with romance, like people and couples wending and sashaying along rues diffuse eclaires, in the City of Light and in les pays.

Also, it's difficult to separate the history of bicycles themselves from that of the Eiffel Tower.  When its construction began in 1887, the "safety bicycle", with a chain-driven rear wheel and a front of equal size or smaller, had been on the market a couple of years.  With it, ridership grew by leaps and bounds--and, for the first time, significant numbers of women were riding--because, as its name indicates, it was safer to ride than the high-wheelers that had mainly been toys for strong young men.  And, in 1888, while the la Tour was going up, John Boyd Dunlop introduced his pneumatic tire, which would further improve the rideabilty of bicycles.



Now, I am neither an engineer nor a scientist, so take what I'm about to say for what it's worth.  I think that another parallel between the development of two-wheelers and the tower is that both taught subsequent inventors and researchers much about the possibilities of metal construction.  Contrary to what most people believe (as I did, until I learned otherwise!), the Eiffel Tower and most bicycles of the time were not made of steel.  Although steel had been around for milennia, methods for making it in large quantities had only recently been developed.  Thus, it was expensive and nobody really knew how to use it in construction.

Thus, the Tower and bikes were made of iron--wrought in the case of the former and cast for bikes.  Monsieur Eiffel's team figured out that the structure they conceived would be best built by placing them at angles to each other.  Around the same time, bicycle frames were evolving into something like the shapes so familiar to us today, as different bike-builders experimented with different placements of, and ways of joining, frame members.

As heavy as wrought iron is, it's still much lighter than stone, the most popular material for large structures at that time, and for centuries before.  And the cast iron used for bicycles (which were sometimes made by blacksmiths) was sturdier than the wood that had been used to make bikes.  While iron bikes were heavier, they paved the road (so to speak) for steel bikes, which could be made much lighter because the fact that the material is stronger means that less of it can be used to achieve the necessary strength.

Of course, the work of Eiffel's team made the creation of other large metal structures, just as the new safety bicycle opened up other possiblities in bicycle (as well as other vehicular) design and construction.  That meant that, while the Eiffel Tower was the world's tallest manmade structure on the day it opened, it would hold that distinction for 41 years, until the Chrysler Building was completed in 1930.  Likewise, the construction methods developed for iron bikes, along with pneumatic tires, made it possible to develop, not only better bicycles, but also automobiles and aircraft.

So, if you find yourself thinking about the Eiffel Towers and bicycles together, just remember that they are linked, not only in romantic images, but also in history and technology.

Knowing that, it seems fitting that the Bikeffel Tower was built in Breckenridge, Colorado from recycled bike parts:

Defining The Season

What's the difference between a late winter and an early spring ride?

Since it's not yet April Fool's Day, this is not a joke.  However, you are free to leave humorous comments.

Here in the Northern Hemisphere, it's been Spring--at least officially--for a bit more than a week.  Some places have had the kind of weather we normally associate with spring for days, or even weeks.  Other places, like Florida, have already had summer-like (at least by the standards of NYC) conditions, if only for a day here and a day there.  On the other hand, there are places like northern New England, much of Canada and the Rockies, where snow still covers the ground.

So what, exactly, makes a ride early spring rather than late winter?  One factor might be the amount of daylight:  There's noticeably more of it than there was even a week or two ago.  And, since Daylight Savings Time began three weeks ago, that daylight (sometimes a gray pallor) lasts to 19h (7:00 pm) or even later.  Of course, the day has begun later, but soon we will have early dawns to go with our late dusks.

That's a fair measure of the seasons.  But the further north one goes in this hemisphere, the more daylight there is.  (Conversely,there is less of it during the fall and winter.) And some of those places are even more packed in snow and ice than this area was after even a series of snowstorms.  For those who are accustomed to such conditions and have studded tires, that might not be such an important factor.  But even such cyclists--some, anyway--do not ride in such conditions.

That brings me to yet another factor in differentiating the seasons:  The number of fellow riders you see on the road or trail. When I rode to Rockaway Beach three weeks ago, I didn't see any other cyclists. Ditto for the ride I took through the Bronx and Westchester a week after that.  But yesterday, I saw dozens of other riders on the bike path that wends its way along the Brooklyn waterfront.  Then again, once I got to the cobblestoned streets around Bush Terminal--deserted on a Sunday--I had them all to myself.  If I go there in a couple of weeks, I'll probably see other riders, though not nearly as many as one encounters on the Kent Street path.

By that standard, the ride I took yesterday was definitely Early Spring, even if the temperature barely broke the freezing mark and the wind whipped against our jackets.
