Abstract
An electrically powered vehicle comprising two wheels, one of the wheels being a front wheel and the other one being a rear wheel. A first of the wheels comprises an axle; a hub portion comprising a rotary electric motor, the rotary electric motor comprising a stator having a stator frame fixed to the axle, and a rotor surrounding the stator and separated therefrom by an air gap, the rotor having a rotor frame coupled to the axle via bearings; and a tire mounted to an outer surface of the rotor frame. A second of the wheels has a hub portion. The electrically powered vehicle also comprises a frame structurally connecting the hub portions of the first and second wheels. An inner surface of the stator frame of the first wheel defines a space for housing a first power supply. An additional power supply is mounted in the hub portion of the second wheel. An electrical cable is carried by the frame for coupling the electrical motor with the additional power supply.
