2101422 9212891 PCTABS00014 The dual wheel driven bicycle utilizes an elongate flexible shaft (50) or cable for transferring rotational motion or torque to the front wheel. In the preferred embodiment, a rear ring gear (34) is mounted on the rear wheel to drive a rear gear assembly (36). One end of the elongated flexible shaft (50) is connected to and driven by the rear gear assembly (36); the opposite end of the elongate flexible shaft (50) is connected to a front gear assembly (55) which engages and drives a front ring gear (56) connected to the front wheel. A freewheel assembly (60) is interposed between the front ring gear (56) and the hub (100) of the front wheel to facilitate cornering. In an alternative embodiment, the freewheel assembly (60) is an integral part of the front gear assembly (55). This invention is applicable to multi-speed and single speed bicycles.
