Abstract
The propulsion drive for tandem bicycles has front and rear pedal systems. A hub fits the rear wheel and there are two transmission chains. The first pedal system has a shaft (33) and at one end a crank (7') and a toothed wheel (20). The other end has a crank (7') and another toothed wheel (13). The second system is similar, with a shaft (32) on the axis of the first and cranks (7) and a toothed wheel (21) on the same side as the other (20). The hub (19) has two bearings (18) on the shaft (32) and a pinion (15) or pinions (16) with a free wheel.
