Technical Information

Security rating
The security rating helps you choose the lock that is most suited to your needs. 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).
Hundreds of different keys to limit the risk of theft. Comes with 2 numbered keys.

Good solid lock but quite small
Used for 2 to 8 weeks
I’d have to recommend you buy a bigger lock for mountain bikes.
Poor quality lock
Used for 3 to 6 months
Although the lock is compact and lightweight the key got stuck in the lock after the first couple of uses.
