The present invention relates to a bicycle lock, in particular to a steel cable that can be directly locked on a horseshoe lock without additional padlocks.

According to, it is generally used to prevent bicycles from being stolen. Metropolises install locks on bicycles, and the known bicycle locks (horseshoe locks, also known as ring locks) are used to lock on the wheels of bicycles so that the bicycle wheels cannot rotate. It is to fix the horseshoe lock on the frame of the bicycle. When it is desired to lock, the C-shaped lock bolt of the horseshoe lock is buckled on the wheel of the bicycle to complete the locking action, but the known horseshoe lock can only be locked on the bicycle. On the wheel frame, the bicycle cannot be connected to other fixed objects (such as: pillars, railings, etc.), so it is necessary to prepare a cable and padlock that can be wound around the fixed object and the bicycle frame to connect the bicycle to the fixed object. To prevent the bicycle from being directly carried away by thieves, it is known that two locks need to be used at the same time to prevent the theft of bicycles, which is time-consuming and cumbersome to use when locking and unlocking.
