We tie up with a bicycle on a wall, and you prepare to theft. A bicycle lock stops bicycle theft. when you don't use lock... You hang it to a handle or you will wind up on a saddle. A bicycle lock is burdensome when you don't use it. There is a lock to have been built in to the back wheel. However, the thing cannot stop that a thief moves bicycle everyone. The reason is bicycle wasn't bound. I propose the lock which isn't burdensome, and is safe.
