A combination lock is placed on the side of the fork or crank assemblies of a bicycle and inserted far enough to insure that the lock remains locked even when the exposed portion of the lock is sawed off. The sliding lock bolts and pin extend through the fork or crank assemblies and end in a fingergrasp cap to permit the operator to unlock the mechanism when the correct combination is set on the lock dials. The pin has at its inner end a crosshead holding a bolt stud that fits into a hole in the crankshaft or into a hole in the stem of the fork when the bicycle is locked. When the combination lock is unlocked, the stud bolt is pulled back out of connection with the hole in the crank or fork, pinned in this position by the operator during use, and returned to the locked position when not in use, as desired. A spring holds the pin in the locked position at all times unless the combination lock is dialed to open it. If the fingergrasp cap end is sawed off the spring inside the crankcase or fork section continues to hold the pin and bolt stud in the locked position. If the lock end is sawed off the fixed,inserted portion of the lock inside the crankcase or fork assembly continues to hold the sliding bolts in the locked position.
