Lithium Ion motorbike prototype is emission and sound-free It goes 0-60 in around 3 seconds, hits close to 100 mph at top speed, and has about a 100-mile range at cruise. The bike is a Yamaha R1 that has been modified to be powered by lithium-ion batteries. The entire engine is missing. So are the tailpipes, radiator, gas cap, transmission and clutch. In their place: a wall of yellow batteries, an AC regenerative motor, an electric throttle and a three-pronged plug, which pokes out from the frame and connects to a standard outlet. The bike retails at $15,000, give me a break a sound free bike, I'd rather stick t o my Harley what a joke.
