An electric bicycle assembly provided with a lightweight, high performance DC electric motor and a tuned centrifugal slip clutch assembly in combination therewith. This bicycle assembly includes a two-stage start-run electric control circuitry which prevents high motor zero rpm in-rush currents which may damage the motor. Another embodiment of this invention utilizes a variable ratio V-belt drive assembly having a centrifugal clutch capability so as to engage and disengage at a predetermined RPM. Another embodiment of this invention is provided with a front wheel mounted regenerating wheel rotor assembly which is adapted to recharge batteries as needed. Another embodiment of this invention utilizes a mechanically actuated multi-stage power control switch so as to selectively provide a start circuit and two or more power control levels in the operational use thereof.
