A bicycle pedal apparatus is provided formed from two identical halves comprising a plurality of holes. A bolt secures the two halves through the holes and projects out beyond the surface of the pedal, thereby performing a dual role of securing the two halves together and serving as a traction mechanism. The pedal bodies rotate about a pedal axle either directly on the axle or on bearings. In embodiments utilizing bearings, two different bearings are used, roller bearings to bear the rotational load and thrust bearings to bear any axial load. The pedal axle can be tapered with a flanged head and resides in a cavity in the pedal body that substantially conforms to the shape of the pedal axle so as to minimize movement of the pedal axle within the pedal body. |
