An electrically powered vehicle has a motor, controller and power supply contained within a wheel compartment. A cylindrical stator frame is fixed on the wheel axle, with an inner surface of the stator frame defining a space for housing the power supply and controller circuitry. A plurality of electromagnet stator segments are mounted on an outer surface of the stator frame. A cylindrical rotor frame is coupled to the axle through bearings. An inner surface of the rotor frame supports a plurality of permanent magnets that surround the stator segments to form a radial air gap therebetween. Mounted to the outer surface of the rotor frame by appropriate supporting structure is a vehicle tire.
