A bicycle gear shifter comprises a shift positioning ratchet provided with a number of positioning teeth, release teeth and drive teeth, a drive member for driving the rotation of the shift positioning ratchet, a mounting member mounted on a bicycle handlebar, a resettable positioning member, a release member for driving movements of the positioning member, a fixing member connected to the mounting member, and an actuating member for driving the shift positioning ratchet to reversely rotate. The shift positioning ratchet and the actuating member are mounted on the fixing member by a rotatable main shaft, the positioning member is sleeved around the rotatable main shaft, and the positioning pawl engages with the positioning teeth. The drive member is sleeved around the rotatable main shaft and is provided with a driving part engaging with the driving teeth. The bicycle gear shifter has a simple and compact structure, which reduces the stroke of the corresponding components during the shifting process, raises the responsiveness of a bicycle shifting process, and allows a cyclist to shift gears quickly while riding. The invention also allows a cyclist to select a direction of operation on the basis of actual requirements for flexible use.
