John Milbank, Bennetts"The Litelok X strikes a formidable balance between cost and performance. This is going to stop a thief cutting through it in any kind of reasonable time, and they’ll most likely move onto something else"

Warren Rossiter, Bike Radar"...armoured with a composite material called Barronium, resisted the attack of our angle grinder for more than 17 minutes. That’s almost three times longer than the previous toughest lock we’ve tested."

Rob Clymo, T3"A quality lock such as this one is a huge hurdle for cycle thieves and could well put them off having a go altogether. In that respect, the LiteLok X1 seems like a bit of a bargain, especially if your ride has cost you thousands to buy in the first place."

Josh Ross, Cycling News"Litelok doesn’t claim the X1 is angle grinder proof, and it’s not, but it takes two cuts to free a bike and a single cut will trash a grinder disc. That’s enough security for most bikes in most situations and it comes without tradeoffs in price and useability."

THE D-LOCK REIMAGINED

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.

Frequently Asked Questions
How long can LITELOK X1 resist an angle grinder for?
The exact time it takes depends on a number of factors like the power of the angle grinder, the type of discs used and the skill of the user. During our own and independent tests we found that X1 is at least 5 times more angle grinder resistant than the current leading d-lock aswell as needing multiple discs to cut it.
How much does LITELOK X1 weigh?
LITELOK X1 weighs approximately 1.7kgs or 3.7lbs.
What is LITELOK X1's locking circumference?
LITELOK X1 has a full-sized locking circumference of approximately 101 x 196mm meaning you can lock more bikes in more places than other armoured u-locks.
Can I attach LITELOK X1 to my bike?
LITELOK X1 is sold with an innovative Twist & Go mount for mounting the lock on your bike frame. The universal quick-release Twist & Go mount fits any bike style and firmly holds X1 in place even on rough surfaces for rattle-free riding.
If you don’t want to use the Twist & Go mount, we have a lock holster solution. We’ve collaborated with Restrap, another great British brand, to create a Lock Holster, which is available as an optional extra for £14.99.
Has LITELOK X1 been independently tested?
Yes, it has been thoroughly tested by Sold Secure and both locks achieve Sold Secure Motorcycle and Bicycle Diamond levels (the highest ratings available).
(Note: Sold Secure is owned and administered by the Master Locksmiths Association (a not-for-profit trade association) and works from purpose built laboratories in the UK.
Who invented Barronium™?
Our founder and CEO, Professor Neil Barron, supported by Innovate UK, worked closely with some of the world’s leading material scientists for over 5 years to develop Barronium™, our ground breaking angle grinder resistant technology.
What is LITELOK X1 made of?
LITELOK X1 is built with Barronium™, a patent-pending anti-angle grinder material that is applied as a permanently fused composite armour, providing maximum cut resistance and protection from angle grinder attacks. The Barronium™ layer repels angle grinder discs.
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.
What is the warranty?
LITELOK X1 is sold with a 3 year warranty to provide peace of mind and covers mechanical or operational faults through normal usage. The warranty does not cover aesthetic wear and tear. It is important to register your lock and keys with us so that in the event that you lose your keys, replacements can be ordered.
