    Product feature
    1. Safety
      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.
    2. Security rating
      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).
    3. Main section
      Links made of hardened steel (65 HRC), one of the highest strength levels available for bike locks. Guaranteed resistance to hacksaws and hammers. Covered in fabric to keep it from scratching the bike frame.
    4. Lock
      Reinforced lock mechanism. Hundreds of different keys to limit the risk of theft. Comes with 2 numbered keys.

    • Bike locked forever

      Impossible to unlock my bike... must be an indoor lock as it rusted really quickly. Bike being chained for weeks now. Tryied all sorts of oil impossible to open it.... if anyone at decathlon reads this and has a solutioon i d appreciate.
      Response of the brand
      Dear sir,
      I can confirm that this is a lock designed for outdoor use. I have used the very same one personally for nearly three years outside. Every few months I apply some spray grease in the lock (not WD40 etc...) but one of the most common causes of locks jamming up is grit and grime. Keeping the lock mechanism off the ground for as long as possible is a good tip.
      Realistically in your case, the only way will be to saw or cut through the chain with a very large bolt cuter or axle grinding machine as this lock is very strong.

    • Not enough to stop theft

      I had great faith in this lock, but have just had my bike stolen with this securing it. It appears a bolt cutter can cut through the metal links.
      Response of the brand
      I'm very sorry to read that a thief stole your bike. It is terrible that this has happened and from my unfortunate personal experience, I empathise completely. This strong chain lock deters many would be thieves, particularly ones of the opportunistic variety. However it is also true to say that some professional thieves carry large bolt cutters and other equipment and given enough time can break through most bike locks. The hardened steel on the links is graded at 65 HRC meaning it is very strong indeed which would have slowed down the thieves considerably.

    • chain very good, padlock not great

      Nice heavy chain, but the padlock is very tempremental. Two or three times now its jammed so that you cant unlock it, the last time it took three of us over an hour to unlock the thing. Will take it back to swap for something else.
      Response of the brand
      Hello,
      I'm sorry to read that the padlock is jamming. Have you tried squirting some grease/oil into the two holes for the U shaped shackle? Try to avoid WD40 which can be OK for un-jamming or to displace water but is also degreaser (which is is not always desirable).
      If you leave your lock out in the rain then this is good practice. If however, you keep your lock indoors or under a shelter then there may well be an issue, in which case, please return it to us for an exchange.
