Abstract: An electric power assist system for use with a pedal vehicle. The system has (a) an electric motorized wheel including a plurality of spokes extending from the motor housing to the rim, at least one the spoke configured so as to define within it a battery compartment in which at least one power supply battery is deployed, wherein the battery compartment lies in the planer region substantially defined by the outer sides of the rim; (b) a wireless throttle control in RF communication with the wheel; and (c) a wireless pedal assist sensor in RF communication with the wheel and configured to detect movement of pedals of the pedal vehicle and transmit command signals to the wheel so as to start power assist operation, and to stop the power assist operation as determined by the movement of the pedals.
