ABSTRACT:
A stroke adjusting attachment for bicycles or the like enables selective changing of the diameter of the orbit which is traveled by a foot pedal to adapt a particular bicycle to persons having different leg lengths or who may have physical impairments which limit foot movement. The pedal is fastened to the attachment rather than being directly secured to a crank arm of the bicycle in the conventional manner. A track member is secured to the bicycle crank arm and the pedal is fastened to a slider which is travelable to any of a plurality of different locations along the track member. Blades extend from the track member adjacent to opposite surfaces of the crank arm thereby maintaining the attachment in a fixed orientation relative to the crank arm. A particular attachment of this form can be fitted onto a variety of crank arms of different sizes and shapes.
