The most common system transmits the movement of the legs on pedals screwed to rods mounted on toothed plates and this drives, through a chain of transmission, a system of free pinion and this in turn to the rear wheel.

The bycicke mechanism are used with chain drive transmission. Bycicle use two simple technique: applying friction in brakes to stop the bycicle and the gearmechanism make the bycicle go faster. Foot are very important to ride a bike because they put the pedals in montion. For this reason we can go wherever we want.
