Abstract
A bicycle hub includes an axle, a main body, a freehub body, and a clutch, which are engaged with the axle, wherein the clutch includes a first ratchet and a second ratchet. The first ratchet and the second ratchet are respectively engaged with the main body and the freehub body. The first ratchet has a first engaging surface, and the second ratchet has a second engaging surface facing the first engaging surface. The bicycle hub is characterized in that a minimum of number of first ratchet teeth on the first engaging surface is seventy-two, and a number of the second ratchet teeth on the second engaging surface is lesser than the number of first ratchet teeth. With such design, when the first ratchet is meshed with the second ratchet, the freehub body could stably drive the main body, and a total weight of the bicycle hub could be decreased.
