Product Customer Reviews

good
This seems sturdy enough. It can be quite fiddly to get the key in the lock.
Lock does the job intended, at a decent price
I bought the product around October 2021 and by December it wouldn’t unlock anymore - causing me being unable to use my bike as well as forcing me to buy a new lock
The lock is long enough to secure a single bicycle to an object. I would not recommend it for two bicycles though (as advertised). The quality appears to be solid, as one would expect from Decathlon. The inside of the lock is a strong chain (and not a cable). Overall, I am happy with the product and its price.
it locks
Good quality lock. Light, flexible, secure and strong.
I read all these reviews about these locks being finicky and getting stuck - so before using I sprayed some MO94 generously in the mechanism and it works a charm. Lock has been smooth though the cold season - you just have to push the key a bit to make sure it gets into the mechanism - no fiddling required! Lock is good combo of length and feeling secure while staying relatively light so you can carry it around your shoulder, seatpost or bag, and easily lock two bikes through frame and wheel. The only minus is that this lock (and other Decathlon chain locks) isn't in the 'Sold Secure' catalogue yet - be aware of this if you have bike insurance that requires your lock to be on the catalogue, these won't do... hopefully something Decathlon can arrange in the future, as these locks are great value!
For the price it's really good
feels solid and long
This lock is brilliant, it's long enough to go around the frame and wheels, and is very reliable/strong.
This lock actually weighs 1,4kg, quite a lot more than stated. Ce cadenas pèse en fait 1,4kg, beaucoup plus que ce qui est indiqué.

Security score
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).(10 being fully theft-proof).
