Problems solved by technology
[0002] Existing bicycle locks are usually U-shaped locks and wire locks. The biggest defect of these two kinds of locks is that the lock bar is exposed, and thieves can easily pinch it off with the miniature hydraulic pliers sold on the market. If the rod is made too thick, it will not only greatly increase the production cost, but also make the lock very bulky and inconvenient to use
