Sprockets are used for bicycles, motorcycles, automobiles, tracked vehicles, and other machines to transfer rotational motion between two shafts, in which gears are not suitable, or are subjected to linear motion of tracks, belts, etc.. Perhaps the most common form of chain wheel in a bicycle, the pedal shaft carries a large sprocket that drives the chain and drives the small sprocket on the rear axle. Early automobiles were also driven mainly by sprockets and chain mechanisms, mainly from bicycles.
