Everything Except The Motor

In the 1960's and 1970's, there was a genre of bikes, at least here in the US, aimed at kids (boys, mainly) by emulating a motorcycle as much as one could without using a motor.

These bikes were often called "muscle bikes" and featured high, wide handlebars, "banana" seats, wide tires and, if they had multiple gears, "stick" controls mounted on the top tube.  (I wonder whether the latter accounted for the decrease in birth rates after the 1970s.)  Examples of such bikes included the Raleigh "Chopper" and the Schwinn "Krate" and "Sting Ray" bikes.

Even the designers of those bikes, however, did not go as far as whoever modified this one:

Hiding Its Power

Cheaters want to win--and not get caught. So they find ways to conceal the ways in which they cut corners.

I don't cheat.  So how can I speak with such authority about cheaters and cheating?  Don't ask! 😉

Seriously, though:  How many ads have you seen for drugs that can't be detected or teas, potions or other things that will make whatever you drank, ingested or smoked the night before "undetectable?" 

Although Jacques Anquetil supposedly said that no one wins the Tour de France on salad and mineral water and the only rider to have won the Tour more often than the "gentle giant" had all of his victories voided because he aimed for "better living through chemistry," taking banned or simply risky or questionable substances is not the only way racers and other athletes have tried to gain unfair advantages.

Over the past few years, riders have been caught with "boosters" concealed in various parts of their bikes.  I am not naive enough to think that all of the riders hiding mechanical and electronic "aids" in whichever parts of their bikes--or clothes or bodies--have been detected.  And, given a development I've just become aware of, I wouldn't be surprised that more will choose not to play by the rules.

Quella, a British company known for urban single-speed bikes (what some call "cafe racers) has developed a line of such machines that aren't what they seem, at least to the uninitated.  At first glance, it might seem like another bike from its flagship Varsity line. (Interesting, isn't it, that it shares a model name with one of the most-maligned and best-selling bikes of all time?)  Actually, it is--except for the rear hub, which is larger in diameter than what one normally finds on such a bike.  Inside that hub are a battery, torque sensor, GPS, Bluetooth and motor.





Yes, you read that right.  That bike has an electric assist, but tries to hide it. Now, of course, I don't think it would get by a race registrar or commissaire but, if someone could figure out a way to fit everything I mentioned into a hub, I am sure that, in time, someone will figure out a way to make such a hub look like the more slender ones we are accustomed to seeing on such bikes.  After all, your Android or iPhone has more capacity than the computers that took the Apollo astronauts to the moon and back.

Also, I imagine that the sensors and motor can be made more powerful, and able to go for longer distances and periods of time on a single charge.  The current system will only push a rider up to 15 MPH with 40Nm of torque--and has a maximum range of about 40 miles on a single charge.  So, this system will only help riders on short rides over flat terrain--which is how such bikes are usually ridden anyway.  

But if (or perhaps I should say when) the engineers figure out how to make the assist go faster and further on a single charge, this system could be a temptation or a boon (depending on your point of view) for some racer who needs a little edge and believes he or she won't get caught--or that the rules or their enforcement will change.

Turning What You Ride Into What You Ride On

Bicycling is commonly seen as an environmentally-friendly form of transportation, recreation and exercise.  Some people ride their bikes for exactly that reason.  And, for the most part, bicycles are less damaging to the planet than many other things, including motorized vehicles.  But there are two bike parts that, too often, end up in landfills.

I am talking about bicycle tires and tubes.  Some of us re-use tubes that have been patched one too many times:  as tie-downs, for example, or underneath clamps to prevent them from slipping and marring a finish.  And, for a time, Pedro's made "Blowout bags" partially from re-cycled inner tubes.  Those bags strapped underneath a rider's saddle and were used to--you guessed it--carry a spare inner tube, patch kit, tire levers and maybe a small multi-tool.

The problem with old tires and tubes is that although they crack from drying out (which is how many Blowout bags, including two I used, met their endings), they don't decompose quickly in the way of some other materials. 

Since 2002, England and Wales have had a law forbidding the disposal of automotive and agricultural tires in landfills. But, interestingly, bicycle tires and tubes were exempt from the law although, according to chemical engineers, they are nearly identical in composition to car tires.





Five years ago, Russ Taylor founded Velorim to bridge this inequity.  He comes from Staffordshire, known for its bull terriers, so it is perhaps not a surprise that he is forward-thinking and ambitious.  He realized that all of those tires and tubes that were being sent to landfills--or overseas--for disposal could be put to better use, not only for consumer products, but in public works.  

As an example, Velorim has developed a process that is now being used to turn pellets from reclaimed rubber goods into a porous material that can be used to lay cycle paths in urban or rural landscapes.  This not only re-uses those old tires and tubes, but also lessens the need to make new asphalt or concrete, both of which involve processes that are harmful to the environment--to say nothing of the fact that asphalt is made from petrochemicals.

So, the tires you now ride could be rolling over...the tires you used to ride.  Somehow that's fitting in more ways than one.
