A bicycle drive assembly may include an axle, a hub shell rotatably mounted on the axle by a first bearing, a free hub rotatably mounted on the axle by a second bearing, and a ratchet mechanism releasably coupling the free hub to the hub shell to transmit torque from the free hub to the hub. The ratchet mechanism may include a first ratchet ring having an inner surface joined to the hub shell for rotation with the hub shell and a second ratchet ring having an inner surface joined to the free hub for rotation with the free hub. The first ratchet ring and the second ratchet ring encircle and radially overlap the first bearing and the second bearing, respectively. At least one spring resiliently biases the first ratchet face and the second ratchet face into engagement to transmit torque from the free hub to the hub shell.
