ABSTRACT:
An electric drive for a diamond frame bicycle which has a pair of upwardly diverging struts connected to the bicycle lug, a pair of wheel mounting struts which extend rearwardly from the lug to carry a driven wheel. A battery in a case is supported by the upwardly diverging struts. A motor carrier is pivotally mounted on the frame adjacent the driven wheel. A motor and a friction wheel are mounted on the carrier and the friction wheel is driven by the motor. The friction wheel has a mounting attached to the frame by adjustable braces to move the friction wheel into and out of a driving engagement with the driven wheel. A circuit which includes a control switch connects the motor with the battery. The battery case, motor carrier and friction wheel mountings have adjustable members which allow them to be mounted on bicycle frames of different configuration.
