FIELD: transport engineering. SUBSTANCE: invention relates to planetary drives built into bicycle wheel hub. In bicycle hub 10 power is transmitted to higher speed in process of speed changing from drive member 22 to holder 43 through second one-way sleeve 51 without use of clutch 45. In process of speed changing to lower speed, switch 49, installed for turning on axle 21 of hub, thrusts cam surface 47 of clutch 45. Driving rotation force transmitted to clutch 45 is converted into auxiliary force axially directed relative to clutch 45 for shifting clutch 45 even in case of high resistance to disengagement of one-way sleeve 50 or clutch 45. EFFECT: provision of easy speed changing at transmission of drive force in motion. 19 cl, 10 dwg
