Great security lock - Highly recommended
"Great lock for your e-bike! It’s highly secure and extremely lighter compared to the competition, very user friendly for commutes. I’m very happy with the purchase so far, and still got my e-bike with me: I guess it’s a great deterrent for thieves."

Great Lock
"This is a brilliant, well considered product. The lock is very light for its type and is beautifully constructed. Overall, very happy with the purchase - highly recommended!"

Loved it so much I bought another one
"Bought one of these as had two bikes stolen from work even with a D lock. This feels genuinely more chunky and leaves less space (but enough) on racks to secure. As I live in a high theft zone I then decided to buy another one for a family member as I was so impressed."

Tried & Tested by Independent Experts
Josh Patterson, The Guardian
"The Litelok X1 is the best overall bike lock we tested. It balances real-world grinder resistance with everyday usability and it is relatively low-weight. This makes it ideal for e-bike riders, daily commuters and anyone locking up in theft-prone areas."
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 Twist & Go Mount which means you can attach the lock to your frame with ease. Both mounts are sold separately.
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 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 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 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.

Excellent product, feels great quality & easily fits through the centre hub of my front wheel. Not big enough to fit around my rear wheel but can fit it through the spokes via the top section of the drive shaft. Well worth the money paid!

I recently purchased a litelock because my previous motorbike got stolen from work
I now own a different bike which I intend to keep
I decided after looking at reviews that I would purchase a litelock. It's feels solid and very well made. I certainly feel my pride and joy is going to.get stolen again.. I would definitely recommend them. Don't wait before it's to late

To try and protect my Triumph trophy 1215 se, i bought two good quality chains from a well known brand, as well as a disc lock and good protective cover, i was appalled with the ease the low life scum cropped off the chains, i got the bike back thanks to a tracker that was installed, once i got her back the first thing i done was to purchase a litelock, wish i had done it sooner, to be honest the price put me off, however after the horrible experience of having your pride and joy stolen and with so much ease it would have been a small price to pay, since i bought my litelock i can sleep at night knowing there bolt crops won't cut it, even now i am considering buying a second one for that added piece of mind, i would seriously advise anyone looking for a bike lock to invest in a litelock, it is money well spent and will save you some real heartache, they may not be cheap but you get what you pay for, for the price of my two chains and disc lock i could have bought a litelock, they say hindsight is a wonderful thing, take my advice, do it right first time and invest in a litelock.

The litelok x1 certainly gives me confidence that my bike will not go missing. It's light and small so not a bother to carry around. It's simplicity is fantastic and it fits through the wheel and tyre on my adv 350 perfectly. It's so good I've ordered another one with the same keys. Delivery was a little longer because of this but 2 locks with the same key is great

Pricey as hell but It works and its hefty as hell , nicely finished astheticly .
Well packed ,and like the little bag but if im going to be picky it losses a star. For the price id expect more postive feeling conections.
The locking end of D lock feels great in one orentation but wiggles and lifts ever so slightly in the other, it lock and is locked but sparks that did i leave the stove on ? Niggle in your head.
Ability to re order and register the keys is great and apriciate the silicone barrel cover but again , lacks finess of a postive CLUNK of the key being in just kind of wobbles until it engages exagerated with chunky cloves on.
My two cents ...Sort out the niggles maybe have the option to order or select for a larger glove freindly keys

I've used my X1 for 3 years in NYC locking bikes and motorcycles daily in Brooklyn and on 5th avenue overnight. Never had an issue or anything stolen. My only wish is a change from the bio-based rubber, it does tend to get beat up pretty quick, but to its credit it stands up to gasoline and oil from my 2 stroke bikes quite well.
Just bought a 2nd. Any competitors cost and/or weigh more.
