<p>A drive assembly for a wheel (1) or wheels is contained wholly within one of such wheels. The drive assembly may comprise an internal power source, e.g. batteries (12), which drives the wheel axle (6) by way of a motor (13) and gear arrangement (26, 27, 28). The assembly is mounted within the wheel (1) by way of a suitably configured housing bracket (16) whereby the assembly is held stationary relative to the axle (6) whilst the wheel (1) rotates thereabout. A roller-bearing clutch (32) may be located inside the lowest gear (28), with the axle (11) passing therethrough. A speed controller (31) may be mounted on the bracket (16) for connection to a remote user-operated control. <IMAGE></p> |
