ABSTRACT:
The ergonomic device bicycles includes an auxiliary crank securable on the end of the pedal crank of a bicycle. An arm portion of the auxiliary crank is outwardly inclined approximately five degrees. Following the installation of the bicycle pedal to the arm portion of the auxiliary crank, the pedal is thereby canted upward by approximately five degrees. By this arrangement, the user's feet are prevented from slipping outward and the vectored force of the feet is transferred at maximum efficiency. Additionally, the outer ends of the pedals are spaced further from the ground and thereby allow for a greater lean of the bicycle in a turn.
