"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."

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.

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.

I feel safe
I like this lock. I know my bike is safe. One comment: I would like some alternatives for mounting the lock on my bike. And the U part rattles a bit during cycling.

LE MEILLEUR U JAMAIS CRÉÉ
Ce Litelok X1 est fabuleux !!! Toutes les autres marques reviennent 10 ans en arrière après cette invention. Il suffit de retourner YouTube pour comprendre à quel point cette technologie est stupéfiante. Et en +, il n'est pas lourd !!! Le service client Litelok est extraordinaire (dédicace à Debra) Bref, mon Bergamont Bakery est parfaitement sécurisé à Paris (France) ;) Bravo LITELOK Mon rêve désormais : la chaine ou le BOA anti-meuleuse et là : on sera au maximum de la folie !!!!!

Great lock, mount not so great
The lock so far makes a really good impression and I hope nobody tries to go against it. The reflective details are also great. The only negative side for me is the frame mount. The idea is quite good, but unfortunately does not work so well. I read that some people believe the mount is very tight on the lock and they have problems attaching and detaching it but with me it is completely the opposite. The lock stays so loose that it is always dancing from one side to the other and going against my legs. Also the rubber where it attaches to the mount is somehow disintegrating with the friction which will for sure make the mount completely useless after some months. Besides that, great lock.

Good
The design is pretty nice. But somehow it feels a bit cheap and my 6 years old daughter ask me why I bought a second hand lock. I don’t mind it if it really works as it says. Could buy x3 for my cargobike but the lock is not certificated by SBSC or SSF here in Sweden. So there is risk that the insurance company won’t pay for it if the bike is stolen.

Thus far, everything is satisfactory.
The lock appears exceptionally sturdy and strong thanks to an innovation material. I acquired it for my cargo bike and although it doesn't appear particularly sizable on that, it most likely would on a regular bicycle. The packaging was pleasant and the overall quality is outstanding. It's satisfying to support an independent producer.
