A bicycle transmission allows a bicycle operator to change the radius of a pedal crank's transmission gear as sliding gear segments, radially arranged on a base ring assembly, vary their relative radial position from the center of the base plate. These gear segments slide in and out to change the effective radius of the gear. Spring biased locking pins engage adjustable control plates as the crank rotates. The locking pins release to make further adjustments to increase or decrease the effective radius. The transmission may also be used as a variable-ratio prime mover for other motive power applications, to transfer power from the wheel to another rotating component. The transfer of power may be via a chain or a belt.
