more Copenhagen Wheel

13 pounds.

It doesn’t have a throttle that lets you just run it like a motorbike. It senses how you ride and gives you a boost when you need it.

Riders are given a boost as they pedal by measuring their effort, instead of using a throttle. This preserves the normal biking experience while enabling riders to bike faster, farther, and easier….All actuation of the wheel happens automatically via the pedals through sensing and control algorithms. When the rider pedals harder, such as when going uphill, the wheel pushes with increasing power. Using your smartphone with the Superpedestrian app, you can vary the level of powered assist.

Shared E-Bikes in SF

Hilly San Francisco to Get Shared Electric-Bikes : TreeHugger.

As awesome as the bike is as a way to get around, sometimes human muscles don’t quite pack enough oomph to deal with hilly terrain.

Especially if the bike, even without the motor, weighs almost as much as a Jetta.

While history shows us it is a natural progression to want to add motors to leg-powered bikes (this is the same impulse which brought us the automobile age), the motor makes the bike potentially much more dangerous while taking away most of its health benefit, neither of which is positive for the beginners who tend to be drawn to e-bikes.

But this is an interesting development in the SF bike share program, no doubt.



China’s electric-bicycle boom

Manufacturers believe exports will grow quickly, especially to Europe and North America, which accounted for more than 70% of the nearly 1m bikes sent abroad in 2009. One in every eight bicycles sold in the Netherlands these days is electric. Better yet, Chinese manufacturers secured an average price of $377 per exported bike, compared with less than $100 three years ago and just $46 for a pedal bike.

The electric bike: Inherits almost all of the disadvantages of a regular bike, and jettisons the health effect. Most of the danger of a motorcycle, without the health benefit of a bicycle.
