Best price/value bike lock for security
If you have a valuable bike or e-bike and/leave It for hours outside you might want to pick one up. Strong, with enough room to lock your bike and not too heavy. One, if not the best in this price range.

Without a Doubt The Best Lock in the World
I invested in an electric bike and wanted to feel that it was secure when out and about. With this lock l can leave it almost anywhere. I live in a very busy city where cycle theft is a very large industry.
Not for my bike though. I have seen cut locks and chains throughout , but mine has not even a touch.
Keep it up Litelok, well impressed

Good luck cutting this bad boy

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.
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.
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'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.

I have just ordered a second lock because the first one was damaged - but it withstood the attempt to be cut off! According to the motion tracker, thieves attempted to cut it for AN HOUR and ended up leaving without the bike.
Huge thanks to Litelok team for making a truly amazing product.

This D lock is a pretty robust solid bit of kit. If you can afford it, go for the X3 which is much heavier and takes longer to cut through.

The Litelok X1 Moto is a fantastic piece of kit. It is a really good size, portable, and comes with a very nice protective sleeve.
However, if you are like me and want to pair it with an 11mm chain to anchor your bike to a fixed object, you might run into a fit issue. I was originally advised to cut the rubber coating off completely, which does work, but there is a much cleaner way to do it.
How to make it fit perfectly:
Instead of stripping the rubber entirely, all you need to do is shave a tiny bit of rubber off both sides of the oval shape at the foot (or both feet) of the D-lock.
Once you shear down those closest inner edges slightly, the 11mm chain links slide right on. It leaves you with an incredibly snug fit and absolutely zero wiggle room. Highly recommended!

As someone who has had a bike stolen (my baby!) - I was scarred about travelling everywhere in London via cycle. I got a new bike and it wasn’t until I saw all the real world testing videos of Litelok that I finally had the confidence to take the new one out.
