Title: Bicycle transmission

Abstract: A collar on the drive shaft of a bicycle pedal hub is mounted with means to displace the collar longitudinally along the shaft. The displacement is accomplished by a limited reverse rotation of the pedals and shaft. The direction of the displacement may be in either longitudinal direction and depends upon the position of the collar before the reverse rotation of the pedals and shaft. Displacement of the collar causes a bicycle transmission to shift gears.
