A bicycle brake device comprises a friction member, a base member, and a piston. The base member includes a hydraulic cylinder. The piston is movable in the hydraulic cylinder in a movement direction so as to move the friction member toward a rotatable member. The piston is at least partially provided in a frame area defined by an outline of a bicycle frame when viewed from the movement direction in an attachment state where the base member is attached to the bicycle frame.
