Abstract: This electric motor vehicle is unique because it has just two wheels parallel to one another. Steering is achieved by the differential rotation of the two wheels with respect to one another—reducing the turning radius of this vehicle to the mere distance between the centres of the ground contact areas of the two tyres. Traction is by two permanent magnet AC motors—the stators on the axle circumference and the rotors on the inside of the wheel hubs. The outer circumference of the hollow axle which doubles up as the vehicle shell; is more than half of the maximum outer circumference of the tyre on the wheel. The heavy-weight electrical energy storage devices, mostly electrical accumulators, are positioned at the bottom of the hollow axle-shell. This brings down the centre of gravity well below the common geometrical centre of the two parallel wheels; providing inertial stability to the vehicle shell, when torque is applied by the wheel motor.
