A bicycle shifting control apparatus comprises a sensing target, a rotational-position sensing unit, and a transmission controller. The sensing target is rotatable with a sprocket assembly. The rotational-position sensing unit is configured to contact the sensing target to sense a rotational position of the sensing target as the rotational position of the sprocket assembly. The transmission controller is configured to control a derailleur based on the rotational position sensed by the rotational-position sensing unit.
