Abstract
A bicycle operating device comprises a base member, an operating member, a piston, and an electrical switch. The base member includes a first end portion to be mounted to a bicycle handlebar, a second end portion opposite to the first end portion, and a cylinder bore. The operating member includes a proximal end portion and a distal end portion. The proximal end portion is pivotally coupled to the base member about a pivot axis. The distal end portion is farther from the proximal end portion than the pivot axis. The piston is movably provided in the cylinder bore and operatively coupled to the operating member to move in the cylinder bore in response to a pivotal movement of the operating member. The electrical switch is provided at the second end portion. The electrical switch is farther from the distal end portion of the operating member than the pivot axis.
