D Lock Bike Security

The one thing you don’t want to happen to your prized two-wheeled possession is to have it stolen. Unsecure bikes make easy pickings for bike thieves so it’s a must that you get yourself a decent cycle lock. A cheap lock might deter the odd opportunist but you should really invest in a strong bike lock …it’ll last for years and it’ll protect your bike from the more determined thief.

One of the most popular style of bicycle locks is called a D lock (so called because it’s shape looks like a capital D. The plus points of D locks are:

• constructed from solid hardened steel bar
• very hard to cut
• easy to carry on board a bike using a bike frame mount
• can offer gold rated security
• available in different lengths

The main disadvantage with D-locks is due to their shape and lack of flexibility. It’s design makes it more difficult to lock your bike to street furniture like lamp-posts, fences and uprights because the steel bar doesn’t bend. If you need a bike lock that offers more flexibility but less security then consider a chain or cable lock (both could be cut by a thief using bolt cutters).

One of the most popular D locks on the market is the Abus Granit X-Plus 54. The parabolic 13mm square section shackle is massively resistant to cropping and twisting. It is securely held in place by the Powercell double locking mechanism with the ease of use of the X-Plus locking system (with illuminated key provided). The Granit X-Plus is a gold rated bike lock.
