ABSTRACT:
Speedometer for cycles and mopeds, of the type by which the measurement is effected by means of a reed relay secured to a stationary part of the vehicle and a number of permanent magnets fastened to one of its wheels, said magnets being arranged to move past the reed relay during the rotation of the wheel. The permanent magnets (4) are molded into a holder (3), said holder being secured to the spokes (2) of the wheel by means of an associated part (14), said associated part (14) being inside the wheel and fastened to the holder (3) in such a way that the two parts (3) and (14) can be secured to the spokes (2) of the wheel. The permanent magnets (4) are positioned in the holder (3) at the same radii from the hub of the wheel, and at the same mutual distance between individual magnets (4). The holder (3) and the associated part (14) can be produced of synthetic material, and said associated part (14) can consist of two half parts.
