Opportunity makes a thief! Even an only attached lock on your bike deters many thieves. This lock is built sturdily because of a braided cable and locks automatically when the cable is inserted into the closing head. This affordable product has a transparent cover and two keys are included with delivery. For all people who would like to have even more safety, we recommend the thicker version with a diameter of 15 mm. Protect your bike effectively and visibly for everyone!
