ABSTRACT:
An extender arm for a bicycle crank arm consists of a generally cylindrical structure suitable for being slidably mounted on the crank arm of the bicycle. The distal end of the extender includes an opening for the mounting of a bicycle pedal. The extender arm contains at least one opening in its side for receipt of a bolt or fastener which will extend through the extender arm and into the opening at the end of the crank arm for receipt of a pedal. In one embodiment, the extender also includes a set screw at the proximal end opposite the distal end on which the pedal is mounted for stabilizing the extender arm on the crank arm.
