The weight is heavy so you know its strong and reliable. Definitely value for money. Only downside was that we had to oil the lock itself after all the rain last year, starting seizing up but a little WD40 and was perfect again. Review: Must buy! - Absolutely perfect.. Thick chain which would be very hard to cut, two keys incase you lose one and everything is very high quality. Also is very long which is nice. ## Features - High security bike lock: With 6mm thick security heavy-duty chain links, our bike chain lock is made of heavy-duty steel known for its cut-resistance. Regular lubrication for the lock hole and keyhole will prolong the lock’s service time. - Protective cloth sleeve & dust proof cover: The chain of this bicycle lock is enclosed in protective cloth sleeve that could effectively protect the chain locks from being rusted and scratched. And the dust cover can protect your keyhole from rain and dust. - Come with two keys: Bike locks will come with a spare key to prevent key loss. The barrel of the lock spins to make locking and unlocking it more convenient, easy to use. Safety tips: Never leave your bike locked outside for long periods of time. Especially in high crime areas. No bike lock is 100% secure. - Portable safe size: The overall length of the heavy bicycle lock is about 92cm. This gives plenty of length to fasten it to railings or wherever you wish to fasten it to. The links are about 5cm long and about 6mm thick. - Widely used: Ideal for bicycles, motorcycles, ladders, lawnmowers, stroller, scooter, fences, tool boxes, sport equipment and etc. Great for tethering your bike to a tree or rail.
