What the experts say...
James Grear, bikelockwiki.com
"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."
Carl Ellis, thebestbikelock.com
"It’s definitely the most secure bike lock I’ve ever tested. And that it manages this without being excessively heavy, bulky, massively expensive or incredibly unpractical, is indeed a BIG DEAL!"
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."
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."
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 thhousands to buy in the first place."

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 can be easily attached to your bike with the innovative X1 Tactical Mount (sold separately) which means you can attach the lock to your frame when the lock is not in use.
Armed with Barronium®
Barronium® fused composite armour repels angle grinder attacks and eats angle grinder discs.
LITELOK X1
Tested to Destruction
Tested against the best-selling 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 U-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's the difference between X1 and X3?
LITELOK X1 and X3 are both highly resistant to angle grinder cuts. This resistance comes from the layers of Barronium® that each lock features. X3 uses a higher amount of Barronium® meaning it has a higher resistance to angle grinder cuts than X1. X1 has at least 5 times the resistance to angle grinder cuts compared to the best selling U-locks whereas X3 has at least 20 times the resistance.
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 independent testing bodies Sold Secure and ART. Both locks achieve Sold Secure Powered Cycle and Bicycle Diamond levels (the highest ratings available) and ART4.
(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.

Let's get the elephant in the room out of the way - this was not designed for motorbikes, and it only fits on some motorcycle wheels, so make sure you've used the template available on the website and ensure it will fit on your bike before buying... Probably great for a little 125 or something of that nature, but won't work on a larger bike in general unless you have the kind of hubs it can go through.
SO that's the only reason this isn't a 5-star review
That aside, it is lightweight, really solid build quality, extremely portable, and does everything I need it to do on one of my bike's front wheels, at least.
Not tested it myself or yet had some thieving little scrote try doing it on my behalf, but I feel a lot better knowing I have it when I'm out and about on my little Himalayan, and wouldn't want to be without it.

I bought this Litelok X1 Moto for my new motorbike, and guess what? It has given me the peace and security I was looking for when it comes to securing my bike. Okay, it's not ballistic attack approved, but when it comes to someone thinking of stealing my bike, they will certainly have to put in more effort than I put into buying this lock. Great job, Litelok! Keep up the good work! 👏

I’m genuinely impressed with the X1 bicycle lock. From the moment I took it out of the box, it stood out with its sleek, high‑quality look, but what really matters is the peace of mind it brings. I can confidently leave my bike locked in public spaces, knowing the lock is solid and dependable and will truly do its job. It feels like a well‑thought‑out product that balances design and security perfectly. Overall, it’s a great investment and one I’d happily recommend to any cyclist who values both style and reliable protection for their bike.

This is my first motorcycle lock, and after doing quite a bit of research I decided to go with the Litelok X1 — and I’m really glad I did.
Right out of the box the lock feels incredibly solid and well made. The build quality is excellent and it immediately gives you confidence that it’s designed to deal with serious theft attempts. One of the main reasons I chose the X1 was its reputation for being highly resistant to angle grinder attacks, which gave me a lot more peace of mind compared to cheaper locks.
One thing that did surprise me at first is that it’s a bit smaller than I originally expected. My initial plan was to use it mainly to lock the bike to something solid, like a ground anchor or street furniture. Because of the size that’s not always possible depending on what you're locking to, but it actually works really well when I put it through the spokes of my motorcycle wheel instead. It still feels extremely secure and is very quick and easy to use that way.
Another thing I really like is how lightweight it is for such a strong lock. It doesn’t feel like a burden to carry around, which makes it much more practical for everyday use. It also comes with a small carry pouch, which is really useful for transporting it—especially if the lock gets dirty from being in and around the spokes.
The locking mechanism feels smooth and reliable, and it clicks shut securely every time. As someone buying their first motorcycle security, I wanted something that would give me real…

As an anxious person it would be easy to psych myself out of ever using my bike properly because I live in a city where bicycle theft is rife.
The X1 gives me the confidence to leave my bike locked up in public without spending the rest of the day fretting. Money well spent.

No longer having secure parking and having to park my bike in the driveway, I was very apprehensive to say the least about moving home. I had the normal sold secure chains and locks but they were cumbersome and I have seen so many videos online where thieve's with angle grinders have still cut through them relatively easily. After being in my new home for a month, sleeping with the window open in the middle of winter, just in case I would be woken up by someone trying to steal my motorbike...I'd had enough. I'd seen some ads for litelock on social media and decided to look into them in more detail and having seen people, even in other countries recommend them...I just went out and bought the X1 hoping it was a worthy investment to try introduce some calm into what has now become a regular activity of checking my bike multiple times a night. I'm so pleased that I bought it and now will be buying a second so I can have one on each wheel and get rid of the awkward heavy chains and locks I currently use on the other wheel. Extremely good quality, easy to put on and a major deterrent to any potential thieves.. it will certainly give me time to react should someone attempt to cut through it. 100% recommended.
