The preferred locking method for motorbikes, scooters and bicycles are chain locks, which are durable and, most importantly, extremely robust.

What Are They Made From?

Premium chain locks use a hardened metal chainlink, which is then wrapped in a super-tough cover. This cover can either be a dense, flexible plastic or a Kevlar lined fabric. Both these additional covers help the fight against pesky thieves, and make it far more difficult for cutting tools to grip and cut into the chainlink. Even if the cover is breached, the chain itself is usually a super-hardened steel-alloy blend; often they have special coatings, or have been subjected to additional workings to make the metal even tougher.

Although they are heavier than their other counterparts, it’s easy to ride with one across your chest or around your waist, which also makes securing your bike a speedy affair.

The weakest link will always be the padlock, as it’s the only component made from more than one part, and is the connection between the two ends of the chain. Most high quality chain locks come with a very robust padlock designed to resist lock-picking and impact damage.

How Much Are They?

Usually, chain locks come in at a higher price point than U-locks and cable locks. This doesn’t mean you should avoid using them however; chain locks combine the flexibility and the robust reliability of both, making it the best of both worlds.

What Features Should I Look For?

Unlike bikes and components, the features of chain locks are not particularly apparent. However, there are certain things you should keep an eye out for:

  • Sold Secure Rating: Look for the highest rating possible required for your bike value. Gold is the highest rating on their scale; you can see who Sold Secure are here.
  • Protective Cover: Any chain lock with a Kevlar cover is going to be pretty hardy against the average thief and their tools.
  • High-Quality Padlock: Being the weakest part of the overall lock, it’s essential that the padlock is extra tough, and resistant to cutting and lock-picking.
