Abstract
An electrically assisted cycle including a frame and a ground engaging wheel rotatably mounted on the frame. A drive member is rotatably mounted on the frame and is arranged to be rotated by the rider of the cycle. A chain couples the drive member and the wheel and there is provided an electric motor and an associated battery carried by the frame, the output of the motor being coupled to the wheel so that the motor can propel the cycle; an electrical switch is incorporated into the rider operated drive member and is so associated with the electric motor that the motor cannot be energized unless the switch is operated by the rider applying a driving force to propel the cycle.
