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

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.

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.

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.

Mountain BikeWhat do you like about this lock? Great Quality, High Security, Angle Grinder ResistanceRated 5 out of 5 starsPerfect bike lock
The lock is excellent. The locking mechanism is very smooth. The lock cylinder protected with a rubber lip is also positive. Only the size of 18 centimeters is a bit too short, for example, if you want to connect the bike to a larger post or if you want to lock two bikes together. Overall, however, the best and most confidence-inspiring bike lock I've ever owned.

I bought this because it is angle grinder proof and offers high security. This level of security comes at a price and I think Litelok X1 is value for money in terms of protection offered.

reassuringly solid and good carrying bracket but lock is so very heavy for my lovely light bike ( litelok is a bit of a misnomer)
Had to wait a long time for it...but guess it will be worth it.

As it stands today it seems to be the most secure lock but we will see.
The only issue I have is weight. Only place to carry it on the trail (eMTB) is in a small rucksack (12/15l) on the back. There is no where to attach it to the frame and it just adds weight to an already heavy bike.
You also have to juggle the keeper plate whilst locking/unlocking the the LOK.
