A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, and a clutch. The sprocket support body is rotatably mounted on the hub axle to rotate about a rotational axis. The sprocket support body is rotatable relative to the hub axle and the hub shell about the rotational axis. The clutch has a first coupling state where a pedaling rotational force is transmitted from the sprocket support body to the hub shell in a first rotational direction during pedaling, a first release state where the hub shell is rotatable relative to the sprocket support body in the first rotational direction during coasting, and a second coupling state where a coasting rotational force is transmitted from the hub shell to the sprocket support body in the first rotational direction during coasting.
