A bicycle shifting device includes a first transmission unit, a second transmission unit, a coupling member and a release unit. The first transmission unit includes a first rotational body, to which human power is transmitted. The second transmission unit includes a second rotational body coupled to the first rotational body and a rotational shaft rotatably supporting the second rotational body. The coupling member is movable relative to the second rotational body in an axial direction of the rotational shaft and configured to couple the second rotational body and the rotational shaft so that the human power transmitted from the first transmission unit is transmitted to the rotational shaft through the second rotational body. The release unit uncouples the second rotational body from the rotational shaft by moving the coupling member in the axial direction using the human power transmitted from the first transmission unit.
