Independent reviews • Best prices • Fast and free delivery
D locks provide the most impenetrable theft protection for your bike. If used properly and attached to an immovable object, they’re pretty hard for thieves to break. For maximum security, use them in conjunction with a cable lock. See our Locks guide for more.
1. Abus Granit X-Plus 54 D-Lock - Sold Secure Gold
Review
The Granit X is a burly yet elegant lock with a broad remit – it works equally well out and about or as a stern shed lock. It’s pleasing to look at, with a barrel that appears tough enough to discourage any would-be thieves.
Both brackets and keys are easy to use with this one, so its meaty proportions make sense for clumsy types. It even has a little light on one of the keys for less of a grapple after dark.

2. Kryptonite New York Fahgettaboudit Mini Lock
Invest in the Best
Review
The New York Fahgettaboudit is the definitive lock of the Noo Yawk hipsters and bike couriers. Yes, it looks great, but if you’re left standing by a broken lock with your pant leg rolled up and no bike, let’s face it, you’ll just look daft. And sad.
Because of this, the mellow yellow New York is armoured up against bolt cutters and leverage, with extra resistance thanks to its small dimensions. It even has Kryptonium in it too, so you’ll be ok if Superman ever goes to the bad and gets into petty bike theft.

3. Master Lock Gold Sold Secure D-Lock Plus Cable
Review
The Masterlock Street Fortnum is a burly and traditional D lock, with a long-arm shackle plus extra cable, making it a very comprehensive security system. The barrel of this lock houses some extreme high security, making it both pick and drill proof.
Due to its weight and as it’s got a dustcover to guard against the weather, this is an ideal lock for leaving in one place where you need to secure your bike regularly, such as the bike racks at work.

4. Kryptonite Evolution Mini 7 Lock With 4 Foot Kryptoflex Cable - Silver Sold Secure
Commuter Essential
Review
The Kryptonite Evolution Mini really is one small but mighty lock. As well as being compact enough to slip into the rear pocket of your jersey, it’s a mighty Sold Secure Silver rated. Part of this is down to the cunning L-shaped bend in one leg of the shackle, making it extra hard to pry. Its compact size also makes it very difficult to get a crowbar in.
The additional cable is ideal for extending the lock’s remit, letting you tie in saddles, wheels and other components to the Evo’s protective influence with the handy Kryptoflex cable included.

5. OnGuard Pitbull DT Shackle U-Lock Plus Cable - Diamond Sold Secure Rating
High tech
Review
The OnGuard Pitbull has a lot going for it if it’s out-and-out security you’re after. This diminutive D lock packs an awful lot of anti-theft into such a tiny package. It’s Sold Secure Gold rated for a start, so it boasts the highest security rating possible.
If that’s not enough, it also has a 120mm steel braided cable thrown in, to protect all your periphery components. Both shackle and cable have protective rubberised coatings to prevent any damage to paintwork.
