100 Bike Accessories Lock with Key - Grey

Contrary to what many people may think, no lock is fully tamper proof.A bike lock is there to make stealing the bike more complicated, to delay the thief and therefore act as a deterrent.A good lock has an anti-picking lock mechanism and is made out of materials which require very specific tools to break or cut through, making theft more difficult.

The security rating helps you choose the lock that is most suited to your use. To accomplish this, B'Twin defined a test protocol jointly with an independent laboratory, CNPP, based on real-life theft techniques. This unique protocol allows each lock to be given a comparable rating indicating how resistant it is to theft. This rating ranges from 0 (least secure) to 10 (most secure).
