The cycle pedals (1) have their orientation controlled by the connection in two distinct points to two distinct transmission axles (6,7) by different cranks (4,5) and rods (8). The arrangement of the axles and the crank and rod dimensions are such that pedal movement adapts to the feet during cycling. The two axles are controlled to rotate together by a chain connection (9). The two axles are located in front of the rear wheel and longitudinally displaced from each other. The short cranks (4), equipped with the rods, are located on the front axle (6). The long cranks (5) are located on the rear axle (7).
