The invention provides a bicycle gear shifter with multi-direction release operation. The bicycle gear shifter comprises a gear shifter shell, a release mechanism and a release stirring rod. A fixing shaft around the central axis, a steel wire rope ring capable of rotating around the fixing shaft, a tensioning mechanism and a disc-shaped part are arranged in the gear shifter shell. The tensioning mechanism comprises a tensioning sector tooth, a tensioning pawl and a tensioning stirring rod. The release mechanism is provided with a moving part, and a positioning pawl for holding operation and a locking pawl for release are arranged on the moving part. The bicycle gear shifter is characterized in that the release stirring rod moves to an action position from a neutral position in the second direction opposite to the first direction, and the positioning pawl and the locking pawl are alternately embedded into a holding sector tooth and a locking sector tooth on the disc-shaped part respectively. The bicycle gear shifter is more reasonable in structure and low in production cost and installation cost, and the number and the installation space of parts are reduced. The bicycle gear shifter is provided with the release stirring rod with multi-direction release operation.
