ABSTRACT:
A pedal primarily for use with an exercise cycle or similar apparatus. The pedal has a top pedaling surface and is counterweighted to retain the pedaling surface substantially in a horizontal orientation. For counterweighting, the pedal is provided with a pair of spaced clamps secured to the pedal beneath the pedaling surface, and an elongated counterweighting body is retained in the clamps. The body is prevented from axially shifting by means of a circumferential flange formed in the body which intersects a corresponding groove formed in one of the clamps. The pedal has an attachment bolt having a threaded free end and an extension located between the threaded free end and the pedal for attachment of an exercising arm.
