Technical Information

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.

lourd mais efficace le prix est elevé
Satisfaite
Used for 3 to 6 months
Très sûr, bien évidemment c'est lourd, j'ai rencontré également le problème de ne plus pouvoir ouvrir l'antivol, car je n'avais pas enfoncé la clé dans la serrure à fond. J'habite en cité universitaire où les vols des vélos se font très courants et tout le long de l'année je n'ai pas eu des soucis à m'en faire.Je suis très satisfaite de cet achat et je vous conseil fortement de l'acheter sans hésiter.
Bien

Costaud..mais un peu lourde
catastrophe - les clés ne tournent plus !
Used for 2 to 8 weeks
Après deux semaines d'utilisation seulement, le cadenas ne s'ouvre plus. Les clés de plus en plus difficiles à tourner.... Mettre 15 min en priant pour que finalement l'engrenage prenne.... Un scandale. Ce produit est du vol. Plus que déçu, scandalisé.
Beaucoup trop lourd

Response of the brand
Bonjour,

merci d'avoir pris le temps de nous partager votre avis sur l'antivol chaîne 900.  

Cet antivol a un bon niveau de sécurité, mais quand c'est une chaîne, cela veut forcément dire : "lourd" (épaisseur des maillons).  S'ils ne sont pas assez épais, ils se coupent trop vite.  Si vous cherchez le meilleur rapport "sécurité / poids", c'est mieux de prendre un antivol U.  Par contre, une chaîne étant plus flexible, permets de s'accrocher a des différents supports (poteau, grille, petit arbre,...) ou un antivol u se fixe presque "que" a un meuble urbain prévu pour les vélos.

Je reste bien sur a votre dispo si vous avez d'autres questions / remarques,
Cordialement,

Wim

2.3 kg certes mais semble très solide ( c'est difficile de tester ) . Le tissu qui entoure la chaine est très pratique et éviter d'abimer le cadre du vélo. 2 clés fournies, ca aurait pu être 3 ( comme sur d'autres cadenas de la marque ) .
Ne s'ouvre plus

Mon antivol ne s'ouvre plus avec ma clé...
Response of the brand
Bonjour,

merci d'avoir pris le temps de nous partager votre avis sur l'antivol vélo 900 chaîne.  

Le fait que l'ouverture de votre antivol est devenu dur / voir impossible avec la clé est bien sur compliqué.  Il y a 2 choses à faire (et a tester maintenant du coup)

- pour l'ouvrir et fermer : s'assurer qu'a chaque fois, la clé est vraiment bien enfoncée jusqu'au bout (sinon, cela peut dérégler la serrure.) 
- comme chaque objet (et surtout les serrures) qui consiste de petit pièces en métal qui doivent bouger entre eux, il est très important d'enlever l'humidité et de remettre un peu de graisse de temps en temps (plus régulièrement par temps pluvieux que par temps sec).  Cela peut se fait avec du AllinOne de la marque B'twin ou du WD40 par exemple.

Dans votre cas, j'essayerai de mettre des bons doses du produit (et bien secouer avec) en essayant de débloquer après quelques cycles.

je reste bien sur a votre dispo si vous avez d'autres questions / remarques,
Cordialement,
