Abstract: A bicycle hub comprises a hub shell each end of which is formed with a receiving portion. The outer surface of the rub shell is clamped by a positioning machine, and the inner surface of each receiving portion is axially pressed to form at least three positioning structures. The positioning structures are formed by the following steps: A. bicycle hub clamping step; B. bicycle hub press forming step; and C. bicycle hub loading step. By such arrangements, the positioning structures of the bicycle hub can be obtained by the quick press forming without affecting the structure strength.
