"It’s definitely the most secure bike lock I’ve ever tested. It manages this without being excessively heavy, bulky, massively expensive or incredibly unpractical, is indeed a BIG DEAL!"

"British-made killer of angle grinders. The X1 combines conveniently light weight, a great mount and truly impressive strength, especially against angle grinding. It’s an expensive lock, but what price securing your bike? I wholeheartedly recommend the Litelok X1."
Warren Rossiter, Bike Radar
"Have I tested a lock as secure as the LITELOK X1 before? No. Will I be using the LITELOK X1 to secure my bike? Definitely.
If you don’t fancy becoming another victim on the police bike theft database, there isn’t a better lock for you than the X1."

THE D-LOCK REIMAGINED
BIKES
E-BIKES
SECURE
Barronium®, our new composite anti-grinder armour, is fused to a hardened fine-grain high-tensile steel core to provide protection against multiple tools attacks, including angle-grinders, bolt croppers, cable cutters, long bars, hammers, chisels and more.
REFLECTIVE
X1 locks are finished with Quartz White retro-reflective vinyl strips along the lock shackle and on the X's at each end. The reflective strips flash in headlights to keep you safe and so you can be seen to be secure.
EASY TO CARRY
LITELOK X1 is sold with an innovative Twist & Go mount that fits any bike style, firmly holding X1 in place on the bumpiest of roads while remaining quick to both affix and remove.
ECO-FRIENDLY
The plant-based eco-rubber outer layer is sourced from 80% non-food grade crops, which dramatically reduces the amount of petrochemical plastic required in the manufacturing of our locks. Due to the nature of these materials, any waste generated during production can be recycled and re-used in our solar powered manufacturing facility in South Wales.
LITELOK X1
ANGLE GRINDER RESISTANT D-LOCK
If you don't own an armoured D-lock then your bike is not protected against angle-grinders, which is increasingly becoming the tool of choice for bike thieves.
LITELOK X1
SOLD SECURE DIAMOND D-LOCK - INDEPENDENTLY TESTED
X1 has been accredited to Sold Secure Motorcycle Diamond, Bicycle Diamond and also meets the ‘Police Preferred Specification’ of Secured by Design (SBD) providing the best deterrent for cyclists and motorcyclists looking to secure bikes, e-bikes and motorcycles.
Litelok X1
BARRONIUM®
Barronium® is a fused composite armour that offers unparalleled angle grinder resistance without adding extra weight. It is a super hard ceramic composite material that repels angle grinder attacks and turns the grinder's energy and force in on itself. Continuous cutting wears down the grinder discs, batteries and ultimately the grinder motor itself.

The X range comprises of three layers of protection:
1. A fine-grain, hardened high-tensile steel core providing inner strength against multiple tool attacks
2. Barronium™ anti-angle grinder armour, permanently fused to the core to repel angle grinder discs
3. A plant-based eco-rubber outer layer is soft to touch, so it won't damage your frame.

I bought two of them for my wife and I. We just purchased two eBikes and wanted something hefty. We also have a cables that we incorporate with the LiteLock X1. Not only does the lock look great but the added cable secured by the lock makes for a definite deterrent to theft.

It's an excellent product : feels strong. It feels safe to know that it's made of that special material that make it hard to grind. And also it's a big plus that it's made in Britain ( whenever possible i prefer to support the companies that build their own local factories in Europe ).
