Abstract
A device for bicycles or other pedal-powered vehicles is fitted with at least one crank that has a pedal at one end and a crank box on the other. The crank box is fitted with a flute and contiguous to a fixed structure fitted with a pin. The movement of the crank is limited by the pin's movement in the flute. The crank box has a torsion spring nested within it. The device is fitted with a braking mechanism of the crankshaft's sprockets, in that these sprockets engage with sprockets of a transmission box, connecting the transmission box to the toothed shaft's box. The sprockets of the transmission box, in turn, transmit their movement to the outer shaft.
