Feels secure

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 feels secure - bike has been locked outside in London for a month without issues so far. 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!

Bike stolen easily

Thieves were able to steal my bike despite the lock, no point in paying for a premium lock, if they want it they’re able to steal it regardless of the lock. Very bulky

Good lock for the money

Really solid lock and at a good price , would recommend

Secondary lock

Bought this to supplement my Tank grade DLock and keep my wheel secure (Not long enough to do both wheels in situ & frame but I knew that prior to purchase). Tough but smooth material covering the chain so it won’t scratch your paintwork. Great value and hope it deters any ‘have a go’ scumbag.

Odolný známek za fajn cenu

Kolo pořád mám, takže asi ok :) Trochu jsem zvědavý, jak si poradí s vlhkostí a nečistotami, vstup pro klíč totiž není nijak chráněný

Dobrý zamek na kolo

Kvalita odpovídá ceně. Jelikož nebyl skladem Abus 8/10 za tisícovku, koupil jsem tento levnější BTWIN 7/10 a jsem s nim spokojený. Klíček je opravdu titerny, ale asi to nemá vliv na bezpečnost.

Super zámek

Pevný, sice těžký, ale kvalitní. Mám ho na eBiku, tak váha nevadí.

I na 3 kola

Zámek působí opravdu kvalitně. Jdou zamknout i tři kola k sobě přes vrchní rámovou trubku a ještě je tam malá rezerva. Jen je potřeba si s koly pohrát aby byli co nejblíže. Snad jen ty klíče působí jak od kasičky.

Super Service

Hat Alles perfekt geklappt! Produkt und Service perfekt!

Solides Schloss mit Macken

Das Schloss ist solide und Hochwertig. Hat auch im Test sehr gut abgeschlossen. Leider ist der Schliesszylinder etwas unpräzise und beim öffnen muss man am Schlüssel etwas rütteln, damit er ganz in den Zylinder rutscht. Schade.

Guten Tag,

Vielen Dank für Ihre Rückmeldung.

Sie dürfen gerne mit dem Schloss in einer Filiale vorbeigehen, um zu schauen, ob ein Defekt vorliegt.

Sportliche Grüsse,

Security rating

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.
