ABSTRACT:
The fundamental principle of this invention is based on the fact that the moment of force or torque is equal to the product of a force and a distance through which the force acts from the fulcrum. The pedal of a bicycle comprises a pair of freely rotatable treads together with a pair of inner and outer plates around a spindle connected to a crank, the spindle, a center tube covering the spindle, and minor parts. The force of man's leg onto the pedal per unit time can be conserved or increased by securing one of the rotatable treads to the spindle by means of a one-way clutch means provided in the space between center tube and spindle in order to enlarge the distance from the fulcrum to the point of action of the force.
