Bicycles with electronic shifting systems and methods

摘要

Electronic shifting systems (24), mechanisms and methods of using the systems to operate a bicycle (20) that allows front and rear gear changer mechanisms (30, 36) to be controlled with only two switches (27A, 27B). The switches (27A, 27B) can be arranged so that each hand is only required to operate one switch (27A, 27B) to shift the bicycle (20).
