A lock assembly for a bicycle may comprise a shackle and a lock body. The shackle may have first and second end portions, and a central portion. The shackle may include a cable disposed in a cushioning sleeve extending between the first and second end portions. A resilient member may be disposed on or included in the central portion of the shackle. The first end portion may include a locking member, and the second end portion may be connected to the lock body. The lock assembly may be operable between stowed position corresponding to the shackle and a portion of the lock assembly contained within a bore of a handlebar of the bicycle, and a removed position corresponding to the lock assembly removed from the bore.
