120 Accessories Combination Cable Lock

Unlike what many people may think, tamper-proof locks do not exist. 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 requiring the use of specific tools, therefore making theft more difficult.

The security rating helps you choose the lock that is most suited to your use. In order to do that, B'Twin has defined a test protocol with an independent laboratory, the 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).
