An auxiliary wheel conversion assembly for a motorcycle comprises a frame
having side members on opposite sides of a receiving space to receive the
rear drive wheel of the motorcycle when connected thereto. The assembly
has a pair of wheels having a common axis but each being independently
mounted to a side member opposite the receiving space, and the pair of
wheels substantially in contact with the ground surface at all speeds and
is not adapted to selectively lift the wheels. The frame also is
substantially at or below the axis of rotation of the rear wheel of the
motorcycle.
