ABSTRACT:
A hub for a bicycle includes a shaft, a hub body, a ratchet wheel, a damper, a drive seat, and a plurality of pawl members. Thus, when the drive seat is rotatable backward, the locking detent of each of the pawl members is detached from the oneway ratchet teeth of the ratchet wheel constantly, so that each of the pawl members will not touch the ratchet wheel to prevent from incurring a noise. In addition, when the drive seat is rotatable backward, the hub body is separated from the drive seat, and rotation of the hub body will not drive the drive seat and the pedal to prevent the pedal from being driven when the hub body is rotated backward.
