Abstract: A bicycle operating device is provided with a position maintaining arrangement that selectively maintains a movable member in any one of a plurality of holding positions relative to a fixed member. The moving arrangement selectively moves the movable member in a first moving direction from a current holding position to another one of the plurality of holding positions. The first operating member moves in a first operating direction from a rest position to a first end position, and moves in a second operating direction from the rest position to a second end position. The movable member is moved by a different number of the holding positions in the first moving direction when the first operating member moves from the rest position to the first end position as compared to when the first operating member moves from the rest position to the second end position.
