Abstract: A cycle is described in which an electric motor is coupled to a chainring or pedal sprocket via one or more chains or belts. The electric motor is also coupled to a sprocket of the rear wheel of the cycle. A clutch mechanism is further included between the linkage coupling the chainwheel and the electric motor such that either the electric motor, the pedals, or simultaneously both can drive the cycle. This design further allows the electric motor to be removed and the cycle to be pedaled normally.
