ABSTRACT:
A speed change mechanism, principally for use on a bicycle, is provided in which a plurality of driving gears and an associated plurality of driven gears are coupled by a plurality of drive chains, such that each driving gear and its associated driven gear form a gear pair, with each gear pair providing a different input-to-output drive ratio. The driving gears are fixedly mounted to a driving shaft that is operatively coupled to a power input, such as a pedal and crank assembly of a bicycle, and the driven gears are rotatably disposed around a driven hub, with means provided for shifting between and engaging one of the driven gears to the driven shaft, with the driven shaft further operatively coupled to an output gear that will transmit power to a rear wheel of a bicycle, for example.
