Abstract
A bicycle shifter includes a base having an annular space and first teeth and second teeth defined in the annular space. A tube is fixed to a center of the base. A first rotation member and a second rotation member are installed in the tube and respectively have a first recess and a second recess. An elastic member is restricted in a space defined between the first and second recesses. The elastic member includes two opposite first and second elastic portions which protrude out from the first and second rotation members. The first and second elastic portions are engaged with the first and second teeth, respectively. When rotating the handle connected with the first rotation member, the first elastic portion moves over the first teeth, the second elastic portion simultaneously moves over the second teeth.
