In this months Popular Science mag there is a Fuel Cell powered bike. It can go up to 20 mph without pedal input from the rider. They say the only problem with it is that Hydrogen(what they use for fuel cells) has a bad habit of blowing up. Also, in making an arguement for why you would want it they say," Have you even tried biking up a mountain?". Little do they know, biking UP a mountain is the best part.
