Abstract
A bicycle hub driving system includes a hub with a socket unit connected thereto. An axle unit extends through the hub and the socket unit. A clutch driving device is located between the ratchet unit and the hub. The clutch driving device includes a clutch unit, a driving unit and a driving member located between the clutch unit and the driving unit. The clutch unit includes a first ratchet portion on the ratchet unit and a second ratchet portion on the driving member. The driving unit includes first driving teeth on the hub and second driving teeth on the driving member. By the linear movement of the riving member between the first driving teeth and the first ratchet portion, the first and second ratchet portions are engaged with each other or disengaged from each other to co-rotate the hub and the socket unit in one direction.
