AWARDED WORLD'S TOUGHEST LOCK 2026
Accreditation
Super strong and secure
This gives me a great deal of confidence. I was initially wary of spending so much money on a lock but considered the cost of the bike and the decision was a no brainer.
It’s remarkably light and quite elegant in its own right.
I like the fact that I can order more keys.

As Good As It Gets
Had my old bicycle stolen with a U-lock from a popular company within seconds. After doing some research I ended up purchasing the X3 for my new ebike. Love this thing. Heavy duty and gives me piece of mind when locking it up outside. It also comes with a pouch I use before storing it in my pannier bag. Highly recommend and worth the investment in my opinion.

What the experts say...
John Milbank, Bennetts BikeSocial
"By having the Litelok X3 as part of that set-up, you’ve made your bike one of the hardest to steal on the street. The Litelok X3 is now my personal choice of portable lock, and very much worthy of a BikeSocial recommendation."
Carl Ellis, thebestbikelock.com
"The Litelok X3 is the most angle grinder resistant portable bike lock I’ve ever tested. And I’ve tested them all now, so that means it’s the most angle grinder resistant portable bike lock you can buy!"
Ben Clarke, Motorcycle News
"X3 Moto has achieved a Sold Secure Diamond rating for bicycle and motorbike applications. And for an added bonus, it’s made in Britain at a solar-powered factory."

LITELOK X3
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 X3 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 X3 is at least 20 times more angle grinder resistant than the current leading D-locks as well as needing multiple discs and batteries to cut it.
How much does LITELOK X3 weigh?
LITELOK X3 weighs approximately 2.1kgs or 4.6lbs.
What's the difference between X3 Bike and X3 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 X3 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 greater 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 D-locks whereas X3 has at least 20 times the resistance.
What is the locking circumference of LITELOK X3?
LITELOK X3 has a full-sized locking circumference of approximately 100 x 195mm.
How do I carry LITELOK X3 on my bike?
If you'd like to carry LITELOK X3 on your bike, you'll need to purchase the X3 Tactical Mount - a tough mount for the world's toughest lock.
Has LITELOK X3 been independently tested?
Yes, it has been thoroughly tested by Sold Secure and both locks achieve Sold Secure Powered Cycle and Pedal Cycle Diamond levels (the highest ratings available). It has also been tested by ART, and certified 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.
What is LITELOK X3 made from?
LITELOK X3 is built with Barronium®, a patented 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.
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 the warranty?
LITELOK X3 is sold with a 7-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.

Having checking the dimensions time and time again I purchased the X3.I wanted the lock to go through both discs and wheel which it does with about 10mm spare.Full piece of mind as we tour all over Europe. Solid bit of kit with a handy bag(pouch) keeping it from banging about in pannier. Had a small wait for it but now having used it can see why there in demand

Having recently had to buy a bike for commuting to work I heavily researched online to find a lock I could trust to keep my bike safe in my garden and at work. This lock absolutely gives me the peace of mind I need and is worth the painful bank statement. It is a hefty piece of gear and the holder is recommended otherwise it needs to be transported in your backpack

Το αγόρασα για την NC750X DCT. Χωράει να πιάσει στη ζάντα και όχι σε κάποιο άλλο σημείο, αλλά ακόμα κι έτσι θεωρώ ότι είναι μια χαρά. Φαίνεται πολύ στιβαρό και ποιοτικό, ενώ κλειδώνει και ξεκλειδώνει εύκολα. Είμαι πολύ ευχαριστημένος με την αγορά.
I bought it for the NC750X DCT. It fits onto the rim—rather than another point—but even so, I think it works perfectly. It looks very sturdy and well-made, and it locks and unlocks easily. I am very pleased with the purchase.

Lock fits round the front wheel, too wide to go through the brake discs though. Doesn't quite fit around the rear wheel either. Would be nice if it was a little wider to do so. Lock works as it should, if a little stiff at first.
