electric bikes that'll hurtle you down the road at 40mph at the twist of the throttle, and there's those who believe pedaling to be enjoyable enough, but would like a less strenuous bicycling experience. If you find yourself a member of column B, listen up, because Gates, NuVinci, and Bosch have created an e-bike concept that'll satisfy your two-wheeled transportation needs. Gates supplied its Carbon electric belt drive, NuVinci brought its N360 infinitely variable planetary hub, and Bosch threw in a battery and control system to make a bicycle beauty. The power train is set up to give riders pedal-assist with four settings that go from Lance to lazy, depending on your mood. At an estimated cost of €2,600 - €3,200 ($3,680 - $4,530), you'll need a bank account comparable to the seven-time champion of Le Tour should an OEM pick up the design.
