The pedal hinge system comprises a hinge interconnecting a footboard and a heel plate, wherein the hinge includes a pair of threaded pins that are each successively fitted into two bearing sleeves with a set screw securely locking each threaded pin in place. The inner bearing sleeve fits into the heel plate to lock the hinge assembly together while the outer bearing sleeve fits into hinge ears of the footboard to insure smoother action and less unwanted play.
