Types of Bicycle Chain Locks Available on the Market

Chain locks usually come in a wide range of lengths and varying flexibility. The longer your lock is, the better will it secure your bike. This is exactly why most people settle for the long locks that can be used for locking up your bike around many different objects.

The locks are also incredibly popular as they are completely immune to the bottle jack attacks as well as your common power tools.

They are tightly secured with links that have to be cut time and again which makes it difficult for the thief to access your bike. In case you’re planning to splurge in the best chain lock, here’s everything you need to know about them.

Chain locks are available 9mm, 10mm, 12mm, 14mm, and 15mm variants. In case you’re wondering what they are and how they work, here’s a quick scoop.

9mm Chain Locks:

While these locks are fairly accessible since potential thieves can easily cut them with medium sized bolt cutting equipment’s, we’d still recommend this since it is more reliable than cable locks. These locks are ideal for people who live in a relatively low theft area or own an inexpensive bike.

10mm Chain Locks:

A perfect balance between practicality and security, these light weight locks are specifically designed for your regular security. While they are not as easily accessible as the 9mm variants, these locks tend to be on the heavier side.

12 mm Chain Locks:

The 12mm locks are meant for higher levels of security and unlike the first two variants, they can’t be accessed with a medium sized bolt cutting equipment. This is one of the best tools if you’re looking for realistic, portable and secure chain lock.

14 mm Chain Locks:

Like the former three products, these locks are not designed for mobile security. Being strong, durable and heavyweight, they need to be left with your bike (overnight). These locks cannot be accessed by thieves, unless they are using a massive bolt cutter (which is very unlikely).

​15mm Chain Locks:

These locks are big, heavy and extremely difficult to be accessed with a bolt cutter. ​
