Meet the Footloose An electric bike, but rather than using a motor to provide assist when pedaling, the only direct link between the pedals and rear wheel is electronic. The pedals power an alternator instead of a chain ring, and send power to a lithium-ion battery pack. That battery powers a motor in the back hub, which is controlled with a thumb throttle. The 250-watt motor is dual-wound, and shifts motor speeds when it encounters a slope, thanks to what the company calls that an “artificial intelligence gear shifter.” No matter the terrain, the rider moves along at a steady pace, pedaling leisurely as if on a bike path through a city park.
