Easy to carry and strong by design, D-Locks are our most popular style of lock. Varying in price, be careful not to spend too little on D-Locks as (similar to most things on the market) the price heavily reflects on the quality. Although structurally sound, some theives won't even need a set of tools to break into cheaper D-Locks; with some good force, you can twist and pop the lock straight off. That's why we reccommend spending as much as you can on security. But beware! If a thief tries to twist a high end D-Lock off your bike, you'll walk back to a nice dink in your bike frame. But at least you'll still have your bike. A good way to stop them from using your bike to twist your frame is by locking it through the rear wheel and the frame, that way you've minimised the amount of room they have to manouver the bike.
A bit more versatile than D-Locks, chains are easier to weave through your bike and lock around stuff on the street. Usually longer in length, they're tough to break into and hard for theives to work with as they tend to move around when trying cut through. Thieves will need tools to break into this style of lock and the weak point will usually be the lock itself so make sure you spend the money as cheap padlocks can be broken into with nothing more than a hammer and screwdriver. The downsides to these locks however, is that they are a bit difficult to carry and the weight of a chain lock is considerablly heavier than that of a similarly priced D-Lock. If you're looking into a lock you can use over night, then chain locks partnered with D-Locks are a brilliant way to combat theft.
Often thinner and lighter than other styles of locks, we usually recommend using a cable as a secondary lock or if you have a cheaper quality bike. The reason behind this is that cable locks are generally the easiest type of lock to cut. Let's split them into two categories; coiled cables and armoured cables. Coiled cables are usually sub £20 and around the thickness of a Sharpie. They're great as a secondary lock for securing a front wheel or saddle but offer little protection against a set of cable or bolt cutters. Armoured cables are thicker, heavier and will do nicely as a heavy duty secondary lock or if your bike looks a little worse for wear and is over looked by most thieves.
