<p>A drive hub (6) configured to mount to the spokes (8) of an off-the-shelf spoked wheel on a vehicle (V) such as, for example, a bicycle, so as to allow said wheel to be driven by a motor (3) mounted to the frame (5) of the vehicle. The hub (6) has an outer face including a channel or belt track (37) for engaging a drive belt (59) from the motor, and the inner side of the hub has formed therein spoke slots (37) configured to accept and lock upon spokes situated on the front or rear wheel of the bicycle, and are situated such that the hub is self-centering upon installation, namely, when all of the slots are lined up to engage spokes on the bicycle, the hub is appropriately centered on said wheel. The hub is driven by a small motor (electric or gasoline) mounted to the frame of the unit, via, for example, a friction belt drive system.</p> |
