ABSTRACT:
A hub for a bicycle includes a shaft, a hub body, a ratchet wheel, a damper, a drive seat, a plurality of pawl members, and a plurality of elastic plates. The ratchet wheel has a plurality of oneway ratchet teeth. The drive seat has a support base which has a plurality of receiving slots. Each of the pawl members has a locking detent. Thus, when the pedal is driven backward (and the drive seat is rotated backward), each of the pawl members is fully hidden in the respective receiving slot, and the locking detent of each of the pawl members is detached from the oneway ratchet teeth constantly, so that each of the pawl members will not touch the ratchet wheel when the pedal is driven backward to prevent from incurring a noise.
