Abstract
A speed indicator for a shifting device of bicycle. The speed indicator is operated by a shifting device which has an arresting face. The speed indicator includes a housing disposed on the bicycle handlebar and provided with a slide portion. A rotating member is pivoted with the housing and provided at one end with a first long hole and at other end with a second long hole. An actuation set is disposed slidably on the housing and provided with an urging rod urged by an elastic member to press against the arresting face of the shifting device. A guide pin is inserted into the first long hole of the rotating member. A display member is disposed slidably in the slide portion of the housing and provided with a guide pin which is inserted into the second long hole of the rotating member. As the shifting device is turned to shift gear, the arresting face urges the actuation set member.
