ABSTRACT:
A rotary drive for a front wheel gear drive bicycle is described in which a front wheel gear assembly disposed on the hub of the front wheel, a torque balancing gear assembly disposed to the head tube of the bicycle, and a pedal gear assembly incorporated into the crank axle at the bottom bracket. They are all interconnected by a rigid coupling and a conventional multiple speed gear assembly can be incorporated in the system to select a preferred riding speed. The front wheel gear assembly, together with the torque balancing gear assembly, allow an efficient front wheel drive with smooth and stable steering and provides a mechanism for a true all terrain bicycle.
