Re: electronic bicycle?
My electric bike is good for exercise and not much else. The one they show would be good for the same. I don't see how it could be fast enough or have enough range to seriously complete with the gasoline engine on a bike, but I maybe wrong someday the battery and generator technology might be there. It could already be there I don't know.
Pedaling the generator would be the same resistance up hill or down hill. It might be able to generate current from the wheels on a downhill run. You would need to pedal almost constantly to keep the batteries up I assume. Still the generator is an idea I never would have thought of.
My posts have entertainment value only. A bike ain't yours till it has your blood on it. Then it owns you.
