I Am Such A Menace!

I guess I shouldn't be surprised to read another article that vilifies cyclists.

Most such drivel blames cyclists for traffic jams and all matter of quality-of-life issues in a city because, if they are to be believed, we all run red lights and run over someone's grandma who's carrying a puppy or a kitten she just took in from the shelter.

Well, there's a new twist on this theme today, in the Washington Post blog.  It starts like this:

  Scenes of Washington life include pedestrians on the streets with headphones, or cell phones or perhaps a purse.  The city's streets are also home to bicycles and bike riders.  And every now and then the pedestrians and the bicyclists do not mix well.

Its author, Martin Weil uses this opener as a Jaws-style setup:  Just as some unwitting swimmer has a cut or barely-concealed body part (a breast, perhaps) that causes the shark to smack its lips and think "LUNCH!", those poor, innocent pedestrians' head phones, cell phones and purses are bait for bad, bad people on bikes.

A real menace 2 society!


Yes, Mr. Weil writes about a string of purse- (and head- and cell-phone) snatchings committed by...a guy on a bike.  Specifically, a young guy or adolescent male on a bike.

Well, I guess I'll have to watch for that when I'm off my bike and crossing a street.  But at least it's good to know that, as a middle-aged woman, I don't fit the profile of the perps Mr. Weil describes.

Now I'm going to tell you a secret:  That's the reason I changed my gender.  I didn't want to seem like the sort of menacing young urban male who preys upon unsuspecting pedestrians at busy intersections! :-)  Heck, I don't even fit the profile of scofflaw cyclists who run red lights and run over old ladies with puppies and kittens.  After all, I really can't bring myself to harm someone when I look at someone and that person is a mirror.

And What Are You Going To Do With That "Extra" Hour?

Daylight Savings Time starts today.  So, if you haven't moved your timepieces ahead one hour, I am nagging  reminding you to do it now.

This means that at the end of this day, you get an extra hour of daylight--to ride, perhaps.

It seems this shop in Florida has other ideas:

Bamboo Or Carbon Fiber: Are Those The Choices?

Bicycles are made either from carbon fiber or bamboo.

At least, if I didn't know any better, that's what I would think after reading an article on The Huffington Post website.


It's one thing for a journalist to be ignorant about a subject before writing about it.  But Tom Levitt, the author of the article in question, seems to have committed a cardinal sin (Well, at least I've always thought it was a cardinal sin!) for a journalist:  not doing his research.

Also, he seems not to know what he is trying to tell his readers.  It would have been fine if he'd stuck to writing a feature piece about the London club whose workshop teaches people how to build frames from bamboo.  That part of the article is interesting enough, at least to me.  I wouldn't even have minded if he'd written about the environmental damage caused by the manufacture or disposal of carbon fiber, or of bicycles generally.  


A class in the Bamboo Bicycle Club's workshop.


But the premise of his article seems to be that teaching people how to make their own bamboo bicycles is a way to mitigate the environmental damage caused by disposing of bicycles.  That, itself, would have been all right if he hadn't conflated the making or recycling of carbon fiber bikes with the making or recycling of bikes generally. 




What's all the more perplexing is that the article includes this photo of share bikes dumped in Shanghai, China.  Again, exposing the environmental damage and sheer waste of such a practice would have been valid.  With my knowledge of bicycles, however, I would say that few, if any, of those bikes are carbon fiber.  Most, I would reckon, are mild to mid-grade steel.  

Why is that important?  Well, steel can be recycled many times without losing strength or other qualities that make it a good structural material.  That is one reason why it's the most-recycled metal.  Not far behind steel in that category is--you guessed it--aluminum.  If any of the bikes in that photo aren't made of steel, they're probably aluminum, which loses little when it's re-used.

On the other hand, carbon fiber is recycled by chopping it to bits and burning off the plastic resin that holds the fibers--which lose significant amounts of their strength in the process--together.  Of course the loss of strength is a concern to bike-makers, but it's even more of a problem in the aerospace industry, where use of carbon fiber has expanded even more than in it has in the bicycle industry.

Carbon fiber use is also expanding more rapidly in the automotive industry, which also might not want to use materials weakened by recycling.  And, for all of the carbon fiber bicycles, boats, gliders, tennis rackets and such available to consumers, the military is still, by far, the biggest user of carbon fiber composites.   Let's just say that the armed forces aren't noted for their concern about the environment, much less recycling.  Moreover, armed forces are willing and able to spend whatever is necessary to obtain the most advanced composites, so they wouldn't be interested in recycled materials.

So...If Tom Levitt had stuck to one topic--bike-building classes, bamboo bikes or the environmental hazards of carbon fiber--he might have written a lucid and enlightening article.  Instead, he has revealed his ignorance or laziness.
