Each plate (10) includes a plate throughbore (64) secured to an end of a drive axle (52) of a bicycle (16). A pedal arm (72) is secured to an attachment post (68) that extends from the leverage plate (10) between the drive axle (52) and a perimeter edge (70) of the plate (10). Moving a pedal (82) on the pedal arm (72) downward to move the bicycle (16) in a forward, desired direction of motion (56), causes the pedal arm (72) to contact the drive axle (52). An inner end (74) of the pedal arm (72) moves the pedal arm attachment post (68) and leverage plate (10) around the plate throughbore (64). The drive axle (52) therefore becomes a fulcrum (52) of a first-class lever (88) as the pedal arm (72) is moved downward. The leverage plates (10) may retro-fit to any bicycle (16).
