Abstract
The bicycle pedal includes a pedal shaft, a pedal body and an abrasive sheet coupled to a shoe engagement surface to enhance engagement of the pedal with a shoe. The pedal body is rotatably coupled to the second end of the pedal shaft. The shoe engagement surface preferably includes a recess with first and second curvatures. The first curvature has a first radius and the second curvature has a second radius larger than the first radius. The abrasive sheet is preferably coupled within the recess. Frictional characteristics are improved by a method including the steps of forming a pedal body with a recess and coupling an abrasive sheet in the recess of the pedal body. The abrasive sheet is positioned to resist peeling of the abrasive sheet from the pedal body. The pedal body can be formed of one or more pieces.
