The present invention relates to a universal fixing member for a device for driving of a bicycle wheel.
Driving systems for bicycles offer assistance for pedalling by means of an additional motor. This assistance generally consists of a drive mechanism arranged on one of the wheels of the bicycle. Thus the power of the motor drives the wheel and is added to the power exerted by the pressure on the pedals, which enables the cyclist to supply less effort.
Unlike the drive system illustrated in European Patent application EP-A-0.155.185, in addition to the familiar drive system the new invention introduces a technological innovation as regards the fixing of the drive device. The fixing member of the drive device comprises a single mounting connecting this element either, in the case of a bicycle, to the seat post or to the handlebars, or to the frames of another non-motorised vehicle. The said system is thus different since rather than being fixed permanently or in a non-adjustable manner to the frame of a non-motorised vehicle, this case provides a truly universe system.
