A bicycle pedal assembly includes a spindle inserted through a thin bearing-less pedal body or an axle formed integrally with a pedal body. The interior of the cage of the pedal body may include a variety of structures or no structures, such as open space. A medial portion of the spindle is inserted substantially through a hollow bolt with an internal passageway. One or more bearings are disposed outside the pedal body and in the hollow bolt to facilitate rotation of the spindle with respect to a crank arm. The bolt is screwed into a standard sized bore of the crank arm. Accordingly, the medial portion of the spindle extends transversely through the width of the crank arm.
