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
Bio Polymer
The natural finish soft plant-based eco-rubber outer layer won't damage your frame
Armoured 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.

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.
What’s the difference between Keyed Alike and Keyed Differently?
Keyed Alike means both locks use the same key.
- You only need to carry one key for both locks.
Keyed Differently means each lock has its own unique key.
- You’ll have separate keys for each lock.
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.
What is LITELOK X1 made from?
LITELOK X1 is built with Barronium®, our patented anti‑angle grinder material, applied as a permanently fused composite armour to provide 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 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.

Unlike the holder, so far I can't fault the lock. Now clearly I don't want it tested otherwise that means someone tried to get my bike, but I hope seeing the lock will stop someone going for it. I know it's a fair bit of money, but I hope long term it does the job and I park my bike up and it's there when I get back.

I purchased two X1’s after reading the reviews and watching the videos on YouTube. They’re very well made and come with a storage pouch and 2x keys. It’s also light weight
I also purchased the bracket so I can secure it to my bike when riding.
Delivered with days of purchase as well.

Great quality lock.
Lock is easy to use and pack in our luggage, bought to update my security in my garage and for our trip around Italy and France, were ot has been faultless up to now (still on holiday)
The only reason I gave it 4 stars instead of 5 is that it could do with being wider to fit around my front tyre and rim, as it won't fit through the disc brake. just a problem with my Guzzi

After seeing lots of video reviews and testimonials of people's experiences of this Litelok, I decided to buy one for my European bike trip. I have always used a chain on my BMW 1250GSA when at home in the garage but now I use Litelok as my primary security lock and am very happy with it.
A suggestion to include a lock reminder cable so you don't drive away with the lock on the wheel!

I had the opportunity to test the Litelok X1 Armour u-lock clasp in a unique Camo painting, which I really liked. I use this clasp every day with my Specialized Turbo Vado e-bike and I would like to share some insights about its ergonomics, safety and everyday use.
Construction and Safety
The clasp gives the impression of being extremely solid. Although it is noticeably heavy, its weight is not exaggerated and does not drastically hinder transportation. The design of the bolt is based on two locking pins, which significantly increases the level of safety. Even in the event that a potential thief manages to cut one side of the headband, the clasp still remains locked and cannot be easily twisted or opened. Although I myself did not test an angle grinder on it, materials and reviews on the network confirm that it is extremely resistant equipment.
Practice of use and fastening
The X1 model in this version is relatively short, which carries with it some limitations. The space inside the headband is small enough that connecting the bicycle frame to the elements of urban infrastructure can be a challenge.
In most cases, the most convenient and optimal solution that I use is to transfer the u-lock through the rear wheel, inside the rear triangle of the frame. The clasp fits perfectly in this space. Of course, in theory someone could throw such a secured bike in a van, but for my needs — when I leave the bike under the store literally for a few minutes — it is quite enough security and gives great psychological comfort.
Mounting Bracket (Frame Bracket)
I carry the clasp in the original Litelok handle mounted on the frame. The very process of removing and inserting the u-lock is simple, although it requires the use of a key (we need to twist the lock to release the lock).
My main complaint is the stability of this solution. When the fastener is inserted into the handle, a small clearance (gap) appears in the lower part. As a result, the u-lock can gently work sideways when driving. In my opinion, the manufacturer could have refined this element better so that the clasp sits in the frame more rigid and stable.
summary
The Litelok X1 Armour is an uncompromising protection that works great during quick stops under the store. Despite the small minus associated with the clearance in the mounting bracket and the limited space of the headband itself, the solidity of the workmanship and the double locking of the lock make me feel calm about my bike.
Advantages:
Armored, very solid construction.
Double locking (two pins) for increased resistance to straining.
Great look of the Camo version.
Disadvantages:
The headband could be a little longer (it is difficult to pin the bike to a thicker pole).
Slight backlash and lack of perfect stability in the original frame mount.

Very easy to use but it would be even better if it was slightly wider.
