A lot of people think that electric vehicles are toys, if you belive this you are in for a suprise... electric vehicles are very cheap, fast and efficient, for instance; it would be easy to build an electric motorbike that would be lighter and beat even the big-bore 2strokes, but the batteries would only last for a couple of minutes- if that. But is soon as they make some really good batteries electric transportation will take off, but they may never make batteries good enough.
Electric transport isn't a space age fantasy, electric cars capable of 70mph have been around for just over 100 years! An electric motor as powerful as a 250cc 2stroke mx motor could weigh as little as 20lbs and be the size of a birthday cake.
So don't underestimate electric!
