"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

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.

I purchased the lock to protect my ebike which I take into the city. It is secure, high quality, and has done its job of deterrence so far. It is a good balance of size and it is lightweight for the level of security. My one complaint would be that the holder isn't fully secure while being held horizontally. It rotates as I ride over bumps which requires me to recenter the lock while riding, and this back and forth is chewing up the nubs on the lock which makes it looser.

I don't really know what to say about a lock in a product review. Maybe that I wish that its resistance will never be put to test! But it really seems very robust. It's very well built, locks and unlocks very smoothly.
I'm satisfied with it

So, the lock is simply perfect. Noy only lightweight but also extremely resistant and with a good size so you can fit the back wheel and the frame.
However, the lock mount twist and lock is very limiting. You can only fit it one or two ways on the bike. I would have much rather preferred a traditional lock mount that you can play around a little bit lore so you can see what fit is better.

Just bought a new carbon gravel bike, and very apprehensive about locking it up in the bike racks at work. I work in hospital... and there have been some thefts. I have a pretty decent ABUS d-lock, but decided I needed to source a seriously good lock to help stop me worrying about it. After some on-line research, I bought the Litelock X1. Very, very pleased with it. Reassuringly heavy, but without being overly-so! It feels like an extremely robust lock. And not so heavy that I can't put it in my bike rucksack. Many thanks for a great product. It's the "seriously good lock" that I wanted!

After the umpteenth bike theft (I stopped counting many years ago at the 12th), I decided to do some research and do my best to try and prevent more. The Litelok X1 should provide that further degree of protection to hopefully deter thieves. It is slightly heavier and less practical than some other locks, but I'm inclined to lean more towards security this time.
