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.

What is claimed is: 1. A bicycle pedal comprising:(a) a one-piece pedal axle comprising(i) an outboard end with an integrally formed flanged head,(ii) an inboard end opposite the outboard end,(iii) a roller bearing coupled to the inboard end, and(iv) a thrust bearing coupled to the outboard end;(v) an o-ring at the outboard end pressing the thrust bearing against the flanged head,(vi) wherein the pedal axle is hollow and tapers towards the outboard end(b) a first pedal body rotatably coupled directly to the pedal axle;(c) a second pedal body similar to the first pedal body and rotatably coupled directly to the pedal axle;(d) the first pedal body and the second pedal body each further comprising(i) an outer surface extending from the outboard end to the inboard end,(ii) an inner surface opposite the outer surface,(iii) a first cavity configured to receive the pedal axle, a second cavity configured to receive the roller bearing, and a third cavity configured to receive the integrally formed flanged head,(iv) a hole to receive a bolt, the bolt comprising a head, a shaft, and an exposed tail, the exposed tail having a length sufficient to protrude beyond the entire outer surface of the first or second pedal body;(v) a recess located on the outer surface, corresponding and leading in to the hole and configured to receive a hexagonal nut or the head of the bolt,(vi) an axle cavity located on the inner surface, journaled to receive the pedal axle,(vii) a locating peg positioned along the inner surface, and(viii) a locating aperture positioned along the inner surface, wherein the locating aperture of the first pedal body corresponds to and is configured to receive the locating peg of the second pedal body and the locating aperture of the second body corresponds to and is configured to receive the locating peg of the first pedal body such that mating of the locating peg with the locating aperture places the inner surface of the first pedal body in direct apposition with the inner surface of the second pedal body and a plurality of holes on the first pedal body are in direct alignment with a plurality of holes on the second pedal body, thereby allowing the tail of the bolt to penetrate through the first pedal body and exit and protrude out of the outer surface of the second pedal body with the head of the bolt lodged in the recess of the first pedal body.
