When using a bicycle, it is common that a bicycle lock is carried with the bicycle wound or kept in a bag. By adding other function to a bicycle lock, portability can be enhanced by fixing it under the saddle working as a safety lamp when using a bicycle. When a bicycle is standing, it can be separated from the saddle and used as a locking device.
