Abstract: The disclosure discloses a bike lock used to lock the bike to prevent bike theft. A first shaft and a second shaft of the bike lock are connected to the handlebar and the front wheel of the bike, respectively. When the bike lock is in a locking mode, the first shaft is not linked to move with the second shaft, preventing the user from controlling the front wheel by the handle effectively. When the bike lock is in an unlocking mode, the first shaft is linked to move with the second shaft. The first shaft can be linked to move with the second shaft by two different linkage mechanisms. One is to link the first shaft with the second shaft with a pin; the other is to firmly engage an engaging structure of one of the shafts to another.

Abstract: A lock for locking a bike is provided. To lock the bike, a user inserts a rope head into a lock through a lock hole. The rope head drives a slider in the lock, and the slider drives a pin, causing an upper-rotation shaft of the lock become not linked to move with a lower-rotation shaft of the lock. Since the upper-rotation shaft and the lower-rotation shaft of the lock are respectively connected to a handlebar and a front wheel of the bike, the user is unable to control the front wheel through the handlebar. The rope head may also be connected to a rope, and when locking the lock, the user pulls the rope out from the lock, wraps the rope around a fixed object, and then inserts the rope head into the lock through the lock hole.
