ABSTRACT:
The pulley of moulded plastics material is mounted adjacent to the outer side of the bicycle wheel flange, concentrically with this flange. The pulley comprises a grooved ring around which extends a belt for driving a distance recorder. From the periphery of the ring, on the side of the latter adjacent to the wheel flange, extend in generally radial directions are three arms which are angularly spaced 120.degree. apart. Mounted on the free end portion of the arms by means of a pivot pin are the end portions of tabs which are provided with a mounting device at the opposite end. This mounting device is adapted to engage with a wheel spoke so as to maintain the pulley in a centered position relative to the wheel flange.
