Abstract

This device for transmitting motion to the wheel 16 of a bicycle 11-12-13 has the characteristic of each having two pedals 4A, 4B connected to a toothed sprocket 1A, 1B for a chain 5, 5A, 5B that is essentially eccentric with respect to the axis of rotation of the pedals, thus creating the maximum traction in the chain 5 when the respective crank 3, 3A-3B is in the horizontal position of moment applied by the foot which is a maximum, the connection of the two pedals occurring indirectly through the action of a common idler shaft or hub 15 that receives the motion of the eccentric sprockets 1A, 1B on their own circular sprockets 7A, 7B, the motion thus acquired can be either transmitted directly to the rear wheel 16 of the bicycle that is connected to the idling shaft 15 or transmitted to a traditional final pinion 28 integrated with the free wheel for use on normal bicycles having a sprocket 26 integral with the idler shaft 15. <IMAGE>
