ABSTRACT:
A shift control apparatus for a bicycle comprises an output transmission member that moves to at least a first output position and a second output position, a position maintaining mechanism, and a release control mechanism. The position maintaining mechanism includes a position maintaining member that moves between a position maintaining position and a position release position, wherein the position maintaining position maintains the output transmission member in one of the first output position and the second output position. The position release position allows the output transmission member to move toward the other one of the first output position and the second output position. The release control mechanism includes a release member that moves between a first release member position and a second release member position. The release control mechanism moves the position maintaining member to the position release position as the release member moves from the first release member position toward the second release member position and allows the position maintaining member to return to the position maintaining position before the release member begins moving back toward the first release member position, or as the release member continues to move toward the second release member position.
