ABSTRACT:
A bicycle of a type capable of wheeling with a minimized pedalling force. The bicycle includes an internally threaded ring gear provided at a free end of a crank arm for applying a driving force to a wheel, an externally threaded gear rotatable in engagement with the internally threaded ring gear. The internally threaded ring gear and the externally threaded gear have a gear ratio chosen to be 2:1. A pedal having a tread is fixed to the externally threaded gear with the tread assuming an upwardly oriented, horizontal position when the free end of the crank arm is oriented forward from a crankshaft providing an axis of rotation of the crank arm and, at the same time, a portion of gear teeth of the internally threaded ring gear furthest from the crankshaft is engaged with the externally threaded gear.
