What the experts say...
Ryan Winiata, wired.com
"Litelok’s trusty X1 offers serious security and impressive versatility for a wide range of users, bikes, and racks. As an angle-grinder-resistant U-lock, the X1’s security scores are among the highest available."
Carl Ellis, thebestbikelock.com
"The best all round bike lock in 2025 is still the Litelok X1. This is because it’s the anti-angle grinder bike lock that provides the best balance between security, practicality and price, for those cyclists that need a higher level of protection."
Jeremy Benson, GearJunkie
"The LITELOK X1 masterfully balances security, price, and performance. In addition to having a slightly larger locking area than most angle grinder-resistant locks, it’s among the lightest and easiest on the wallet."
Mike Stead, road.cc
"The Litelok X1 is one of the lightest Diamond-rated D-locks around. Even more impressive is that for the 1.7kg weight it's a full-size lock with large internal locking dimensions. And it was the cheapest lock to survive our angle grinder test by a long way."
Warren Rossiter, Bike Radar
"The best-value angle-grinder resistant lock we’ve ever tested. When I tried to cut it with an angle grinder, it took 4min 38secs (including disc changes) to cut through one side of the X1’s shackle, which exceeds its premium rivals and the Sold Secure Powered Cycle Diamond rating."

What Makes the World's Best Bike Lock?
LITELOK X1 is the only full-sized armoured D-lock on the market and contains a host of clever design features that make it easy to use and carry so you can keep your bike secure against the most determined bike thieves.
Lock Cylinder
X1 features a high-quality lock cylinder which is durable and pick-resistant. The keyhole is protected from dirt, dust and moisture with our innovative self-sealing silicone keyhole cover.
Reflective Strips
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 seen.
Anti-Rotation
Unique anti-rotation feature protects against twisting attacks and single cuts
Easy to Carry
X1 is compatible with our innovative X1 Tactical mount and the Twist & Go mount which means you can attach the lock to your frame with ease. Both mounts are sold separately.
Armed with Barronium®
Barronium® fused composite armour repels angle grinder attacks and eats angle grinder discs.
LITELOK X1
Tested to Destruction
Tested against the most D-locks on the market, LITELOK X1 is at least 5 times more resistant to angle grinder cuts. Additionally, X1 requires multiple discs to cut and due to its anti-rotation system, needs to be cut on both sides to remove.
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
Can X1 be cut with an angle grinder?
Unfortunately, all locks can be cut with the right tools and enough time. 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 as well as needing multiple discs to cut it.
How much does LITELOK X1 weigh?
LITELOK X1 weighs approximately 1.7kgs or 3.7lbs.
What's the difference between X1 Bike and X1 Moto?
There is no difference between the Bike and Moto versions. They are exactly the same locks. The reason why we differentiate them is to show how X1 can be used as an effective security device for all types of bicycles and motorcycles.
What is the locking circumference of LITELOK X1?
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 compatible with our innovative X1 Tactical mount for mounting the lock on your bike frame. The X1 Tactical Mount fits a wide variety of bikes and e-bikes ensuring your LITELOK X1 is held securely even the roughest of terrain.
X1 is also compatible with the Twist & Go mount.
Both of the X1 mounts are sold separately.
Has LITELOK X1 been independently tested?
Yes, it has been thoroughly tested by Sold Secure and both locks achieve Sold Secure Powered Cycle 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 from?
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.

Bought this in preparation for the ABR festival and being paranoid about leaving the bike on its own for long periods of time, also in preparation for various tours planned in 2025 / 26 . Delivery was next day (I did pay the extra) and packaging was high end. The lock comes with a really nice storage pouch and is "weighty" enough to give confidence in it performance but not to big to sit in my back box. I do like the rubber protection to stop it scratching any paint or alloy wheels, Still undecided as to weather i should have gone for the bigger one (X2 i think) but this does go around the swing arm of my BMW GS so not wholly reliant on just the spokes - see my video. All in all super impressed, so with this on the back wheel through the swing arm and a disc lock on the front I'm pretty comfortable.

Feels like a decent bit of kit!!! Plenty big enough to go through the disc and spokes of my Scramber 400x. Hopefully it never needs to be tested, but really pleased with it!

I was fortunate to be part of a group of women motorcyclists invited to spend an afternoon with the fantastic team at LITELOK HQ in Swansea.
It was such an eye-opening experience. A few of us brought along our own locks — decent ones — and watched them get put to the test with an angle grinder. It was shocking how quickly they were cut through.
Then the LITELOK took its turn, and wow the difference was clear! The grinder discs wore down fast, while the lock barely had a scratch. It was seriously impressive.
Now, when I lock up my bike, I feel a whole lot more confident. It would take a very determined thief with time, tools, and patience to get through this. Plus, the bold design and big X make it a clear deterrent.
I love my bike and with my LITELOK, I have real peace of mind when I leave my bike.

Great Quality, Value for Money, Angle Grinder Resistance, High Security, PortableReviewingLITELOK X1Rated 4 out of 5 starsGreat lock, mounting not ideal (with my bike)
I did research on the internet and this one came out as one of the best. I saw a video on YouTube where they try to sharpen multiple locks. It lasted 3.44 minutes with a diamond blade, and that was only one side. So a total of 8.18 minutes. Search for “we destroyed 6 of the best bicycle locks”
The lock included free fasteners, but I didn't click that when ordering. It was then sent neatly, I just had to pay the shipping costs. It came in a sturdy bag (see photo), which is nice. I emailed with the company beforehand, the confirmation would always fit. That's wrong because I have a triangular frame and no horizontal rod. The material will rotate because you have to wobble to get the lock into the holder (it's quite difficult at first). It can't be mounted anywhere else, so just transport it in the bike bag. Because it is an expensive lock, I am disappointed that the white stripes on the front are just stickers that damage immediately. The white x's on the front side of the lock are made of the correct material. Furthermore, I am satisfied.

Cant find anything to fault with this lock. The squared off shackle stops anyone cutting only one side and spinning it off so they will have to cut both sides.
The key slot has what looks like a silicon cover so no need to flick, slide or remove a cover to insert the key which is a simple task but the key cover makes it easier on this lock compared to others.
Mine came with the tactical mount which i will using, to be fair it is a sturdy lock so dont expect a light weight lock. it does have some weight to it. Cant complain if you need security.
I really hope the lock never gets tested and the sight of it on my bike is deterrent enough.
