ABSTRACT:
A speed indicator for bicycles for indicating the shifting action of the bicycle and a speed sign at each state of shift includes a driving wheel driven by a takeup reel of a shifting device, a resilient strip driven by the driving wheel, and a track along which the resilient strip may displace. When the resilient strip displaces along the track, a shift sign pre-formed on the resilient strip may be shown through an indicating element provided on the track. The resilient strip may be adapted for use in vertically or horizontally oriented tracks of any construction, and their assembly is easy. The driving wheel further includes a compensation mechanism for ensuring clear indication of the indicated sign on the resilient strip.
