Abstract

The invention relates to a multispeed gear system for bicycles. The gear system contains an axle (1) which is rotationally fixed on a bicycle frame, a drive mechanism which is rotationally mounted on the axle (1), a sleeve (12) which is rotationally mounted on the axle (1) and a planetary switch gear (15) with at least one sun gear (19) which is rotationally mounted on the axle (1), a ring gear (24), a sun wheel (17) and a planetary wheel (18) rotationally mounted thereon, in addition to a shifting device (26) to produce at least two transmission ratios between the drive mechanism and the sleeve (12), wherein the shifting device (26) has toothed gearing (77), a ratchet (74) and a determined rotationally mounted actuating member (76) for the control of said elements which can be operated from outside the sleeve (12), enabling the ratchet to engage with or disengage from the toothed gearing (77) to select the transmission ratios. According to the invention, the toothed gearing (77) can be found on the sun gear (19), the axle (1) has a section which is configured as a hollow body and which receives the actuating member (76) and the ratchet (74) is mounted in an opening (83) of an outer wall of said section, defining the hollow body.
