Bicycle electricity generator and a method of attaching the electricity generator to a bicycle
 A bicycle electricity generator is provided including an annular stator and an annular rotor, both of which are coaxially mounted on a bicycle wheel axle in a position between a bicycle wheel hub and a fork, wherein the stator is fixed either on the wheel axle or on the fork; the rotor is fixed in connection with the bicycle wheel hub, the rotor's rotating center being coincident with the rotating center of the bicycle wheel; a rotating force transmitting member made of a resilient material for transmitting a rotating force from the hub to the rotor is provided in a position between the rotor and the hub so as to form frictional engagement with both the rotor and the hub, wherein either an auxiliary transmitting structure is provided for auxiliarily transmitting a rotating force from the bicycle wheel hub to the rotor and wherein one portion of the auxiliary transmitting structure is fixedly secured with respect to the rotor and another portion of the auxiliary transmitting member is fixedly secured with respect to the bicycle wheel or one or more spacers are disposed between the rotor and the rotating force transmitting member and the one or more spacers are in frictional engagement with the rotor and the rotating force transmitting member.
