Bicycle hub

A bicycle hub includes a hub axle (10) and a hub shell including a first tubular member (11) having a first hub flange (11a) secured thereto and a separate second tubular member (12) having a second hub flange (12a) secured thereto. Bearings (13) are disposed between the hub shell and the hub axle (10) for rotatably supporting the first tubular member (11) and the second tubular member (12) relative to the hub axle (10). A generator mechanism (30) is housed in the first tubular member (11) and adapted to generate electricity by rotation of the first tubular member (11) relative to the hub axle (10), and a brake force adjusting mechanism (40) is housed in the second tubular member (12) and adapted to limit a maximum damping force of a brake (80).
