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 requiring the use of specific tools, making theft more difficult.

High-Security Lock. Safety level rating: 8/10 for the D, 1/10 for the cable. The security rating helps you choose the lock that is most suited to your needs. 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).

Hardened steel, tubular shackle for superior resistance (to bolt cutters, saws and hammers). Rubber coating to stop the lock banging against your bike and prevent it from damaging the paintwork. Inner shackle length: 15 cm.

Abloy anti-picking lock mechanism. Hundreds of different keys to limit the risk of theft. Comes with 3 numbered keys.

This kit contains a high-security D-lock plus a cable. The D-lock allows you to secure your bike by attaching your frame to a fixed point. The cable is great for securing accessories and components such as your wheels, saddle, bags, helmet, baby seat, etc.
