For use with a bicycle having a main pedal shaft journalled in a hub, the improvement comprising a pedal crank assembly comprising a pedal crank mounted on each end of said main shaft in axial normal relationship thereto, a shaft-forming element secured to each pedal crank in the end portion thereof remote from said main shaft and extending laterally from the related crank, the longitudinal axis of said shaft-forming member constituting a pivot axis, pedal means provided upon each shaft-forming element for rotation about said pivot axis, each pedal means comprising an annular support plate having a peripheral, inwardly turned flange providing an outer circumferential surface, each of said plates further having a central outwardly opening recess having a side wall concentric with said flange and a base wall, with an opening therein, a bearing assembly fitted within said recess, said shaft-forming element projecting through said recess base opening and operatively engaged to said bearing assembly, a foot supporting member carried by each pedal means having a foot-receiving surface located downwardly of said pivot axis when in operative position.

For use with a bicycle having a main pedal shaft journalled in a hub, the improvement comprising a pedal crank assembly comprising a pedal crank mounted on each end of said main shaft in axial normal relationship thereto, a shaft-forming element secured to each pedal crank in the end portion thereof remote from said main shaft and extending laterally from the related crank, the longitudinal axis of said shaft-forming member constituting a pivot axis, pedal means provided upon each shaft-forming element for rotation about said pivot axis, foot supporting means carried by each pedal means having a foot-receiving surface located downwardly of said pivot axis when in operative position, and a bracket carried on said pedal means in upwardly spaced relationship to said foot receiving surface and above said pivot axis, and an upper foot engaging arm swingably supported from said bracket.

A bicycle comprising a frame having front and rear axle mounted wheels, a hub supported by said frame, a pedal crank assembly comprising a main shaft journalled in said hub, a pedal crank in axially normal relationship to said main shaft mounted on each end thereof, a shaft-forming element secured to each pedal crank in the end portion thereof remote from said main shaft and extending laterally from the related crank, the longitudinal axis of said shaft-forming element consituting a pivot axis, pedal mounting means disposed upon each shaft-forming element for rotation about said pivot axis, foot supporting means carried by each pedal mounting means having a foot-receiving surface located downwardly of said pivot axis when in an operative position, bearing means incorporated in said pedal mounting means and engaging said shaft-forming element to render said pedal mounting means rotatable thereabout, said pedal mounting means being of post character incorporating an extension projecting laterally outwardly at the upper end thereof in overlying relation to said foot-receiving surface, and an upper foot engaging element pivotally carrying said extension for swingable movement between a downwardly directed, operative position and an upwardly and outwardly swinging, inoperative position.

A bicycle as defined in claim 33 and further characterized by means provided on said extension for elevating and lowering said upper foot engaging element.
