The bicycle is constantly being updated in order to meet market needs, the developing trend of bicycle shifting gear has changed from manual shifting fashion into automatic shift fashion. In this paper, a systematic approach is proposed to synthesize the design concept of the three-speed automatic speed changer. In this paper, we accord to the design(More)
Recently, bicycles are used as exercising machines and traffic vehicles. Planetary gear trains can be used as the transmission systems for bicycles. The purpose of this work is to propose a design methodology for the kinematic design of automatic gear transmissions with planetary gear trains for bicycles. First, applying the check list method (combining and(More)
