摘要: A hub assembly includes a first and second pawl units respectively connected to the tubular portion of the hub. A toothed collar is mounted to the first and second pawl units, and has ratchet teeth defined therein. The first pawl unit has three first pawls which are located at equal angle to each other. The second pawl unit has three second pawls which are located at equal angle to each other. An angle is defined between the first and second pawls next to each other, and the angle is smaller than the angle of each ratchet teeth of the toothed collar. The first and second pawls are engaged with the ratchet teeth not simultaneously so as to effectively drive the bicycle and the strength of the pawls is maintained.
