Armoured with Barronium®
Barronium® fused composite armour repels angle grinder attacks and eats angle grinder discs.
LITELOK X1 PLUS
Tested to Destruction
Tested against the best-selling U-locks on the market, LITELOK X1 PLUS is at least 5 times more resistant to angle grinder cuts. Additionally, X1 PLUS requires multiple discs to cut and due to its anti-rotation system, needs to be cut on both sides to remove.
LITELOK X1 PLUS
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 PLUS 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 PLUS 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 PLUS weigh?
LITELOK X1 PLUS weighs approximately 1.99kg (4.39lb).
What's the difference between X1 PLUS Bike and X1 PLUS 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 PLUS can be used as an effective security device for all types of bicycles and motorcycles.
What's the difference between X1 PLUS and X3?
LITELOK X1 PLUS 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 PLUS. X1 PLUS 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 X1 PLUS?
LITELOK X1 PLUS has a full-sized locking circumference of approximately 101 x 255mm meaning you can lock more bikes in more places than other d-locks.
Can I attach LITELOK X1 PLUS to my bike?
LITELOK X1 PLUS 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 PLUS is held securely even the roughest of terrain.
The X1 Tactical Mount is sold separately.
Please note: The X1 PLUS used with an X1 tactical Mount will only be suitable for large frames.
Has LITELOK X1 PLUS 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.
What is LITELOK X1 PLUS made from?
LITELOK X1 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 rubber outer layer that 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 X1 PLUS 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.

Have had our beloved mountain e-bikes stolen from our garage with the gold standard padlocks, chains & ground anchors just sliced through, obviously with a battery angle-grinder, we looked around for more secure locks. Came across the very impressive video & true-life stories showing how (almost) impossible it was to cut through the Litelok X1 & X1 plus, so hit the credit card & bought one of each. Now when we are out & about with the bikes on a bike rack, or outside a coffee stop or stored in our garage, we feel so much more confident that they are safe. Thank you Litelok!

Was worried that it wouldn't fit my BMW S1000XR as many people say they are too narrow for a rear wheel(didn't really want it on the front, too easy to lift, I know the back can be lifted but it's harder). Goes on from right to left, around a spoke & through a hole in the swingarm! They'd have to cut either the X1 or swingarm(twice)/spoke & drivechain! That may take a while! Still say they need to be wider, & why only 2 keys with it when the core moto that I bought with it comes with 3?

Great lock, easy to use, fits in various positions on my bike on both front and rear wheels.
The lock would benefit from the shackle being an extra 1.5cm wider to enable it to go over a sport bike wheel & tyre.

Took our Litelok X1plus x2 to Europe to keep our bikes secure, we also have 2 core moto 125s that we fasten together and then fasten both bikes together to an immovable un cut able object. We felt secure leaving them for a few hours while visiting places, and overnight at our accommodation. First class pieces of kit !

It's good to have a grinder resistant U lock but to eliminate the lifting and taking away linking two bikes together really makes it difficult for theives to complete the job.

Shortly after getting this lock i had a four day tour in Scotland. My X1 plus easily went through the front wheels of mine and my friends bike locking them together, which obviously makes the bikes more secure than a disc lock which i have always used in the past.
My friend is impressed with the lock and he is going to buy one too.

I bought two of these locks to add an extra layer of security to both of my motorcycles. I specifically purchased the X1plus because it is easy to store and carry, but most importantly actually fits my yamaha xvs1300 which other similar locks do not. The extra peace of mind knowing it makes the theft of the bike very much more difficult is priceless.

Bought the X1 Plus as I was going touring in France with a friend and wanted a lock that would secure two bikes. Great bit of kit and felt comfortable in locking the bikes up overnight at hotels in areas we didn't know. Would absolutely recommend.
