Bicycle gear mechanism. View of the gear mechanism on the rear wheel of a bicycle. Attached to the rear axle,this gear mechanism consists of toothed cog-wheels of various sizes. The cog-wheels work to transform the rotary motion of the bicycle chain into wheel rotation. The combinations of small and large cog-wheels produce a combination of slow to fast wheel rotation,making pedalling the bicycle more energy efficient | |
