A bicycle rear hub includes a hub spindle, a drive part, a hub shell and a driving force measuring part. The drive part is rotatably supported on the hub spindle, and configured to receive a driving-force-input member. The drive part includes a coupling part having a liquid storage area filled with a liquid. The hub shell is rotatably supported on the hub spindle and operatively coupled to the coupling part of the drive part for rotation by the drive part on the hub spindle. The driving force measuring part includes a liquid pressure sensor that detects pressure of the liquid in the liquid storage area of the coupling part of the drive part.
