23. Stealth Bomber
For: The off-roader
Part mountain bike, part motocross bike, the Stealth Bomber promises off-road speeds of unto 50mph (you're only allowed 20mpg on the road) thanks to the direct drive, brushless electric motor with only one moving part. It only takes two hours to charge, with braking energy converted to power to extend battery life. In terms of pure pedal power, there's a 9-speed, twist-grip gearbox.
