Got a problem with the various gear and brake cables winding their way around your bike frame? If you're riding a standard pedal-powered bike, the answer is probably 'no.' But if you're one of the increasing numbers of people getting around town on an electric bike than your answer may be different, with faulty wiring one of the most common sources of failures found in such vehicles. While some hide their electrical wiring away inside the frame, many e-bikes have wires running down the outside. Like so many of today's electrical devices, the new Shadow Ebike does away with this unsightly mess and potential point of weakness using wireless technology.
Toronto-based Daymak Inc. has dubbed its Shadow Ebike "the world's first wireless power-assist electric bicycle." Through the integration of ISM 2.4 GHz wireless using frequency-hopping spread spectrum technology to prevent interference, the Shadow has no brake or gear cables, and no visible electric wires running from the motor to the batteries, the controller or throttle. Turning the electric motor on or off, the magnetic regenerative brakes, the throttle and the pedal assist are all controlled wirelessly via the Daymak Drive controller.
