What the experts say...
James Grear, bikelockwiki.com
"If you don't fancy becoming another victim on the police bike theft database, there isn't a better lock for you than the X1."
Carl Ellis, thebestbikelock.com
"It’s definitely the most secure bike lock I’ve ever tested. And that it manages this without being excessively heavy, bulky, massively expensive or incredibly unpractical, is indeed a BIG DEAL!"
Warren Rossiter, Bike Radar
"...armoured with a composite material called Barronium®, resisted the attack of our angle grinder for more than 17 minutes, That's almost three times longer than the previous toughest lock we've tested."
Josh Ross, Cycling News
"Litelok doesn't claim the X1 is angle grinder proof, and it's not, but it takes two cuts to free a bike and a single cut will trash a grinder disc. That's enough security for most bikes in most situations and it comes without tradeoffs in price and useability."
Rob Clymo, T3
"A quality lock such as this one is a huge hurdle for cycle thieves and could well put them off having a go altogether. In that respect, the Litelok X1 seems like a bit of a bargain, especially if your ride has cost you thhousands to buy in the first place."

What Makes the World's Best Bike Lock?
LITELOK X1 is the only full-sized armored U-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 can be easily attached to your bike with the innovative X1 Tactical Mount (sold separately) which means you can attach the lock to your frame when the lock is not in use.
Armored 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 U-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 armor 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 U-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 armored 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 that is applied as a permanently fused composite armor, 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 armor, 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.

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!

Miałem okazję przetestować zapięcie u-lock Litelok X1 Armour w unikalnym malowaniu Camo, które bardzo przypadło mi do gustu. Zapięcie to użytkuję na co dzień z moim e-bike'iem Specialized Turbo Vado i chciałbym podzielić się kilkoma spostrzeżeniami na temat jego ergonomii, bezpieczeństwa oraz codziennego użytkowania.
Budowa i Bezpieczeństwo
Zapięcie robi wrażenie niezwykle solidnego. Choć jest odczuwalnie ciężkie, jego waga nie jest przesadzona i nie utrudnia drastycznie transportu. Konstrukcja rygla opiera się na dwóch bolcach blokujących, co znacząco podnosi poziom bezpieczeństwa. Nawet w przypadku, gdy potencjalny złodziej zdołałby przeciąć jedną stronę pałąka, zapięcie nadal pozostaje zablokowane i nie da się go łatwo przekręcić ani otworzyć. Choć sam nie testowałem na nim szlifierki kątowej, to materiały i recenzje w sieci potwierdzają, że jest to wyjątkowo odporny sprzęt.
Praktyka użytkowania i zapinanie
Model X1 w tej wersji jest stosunkowo krótki, co niesie ze sobą pewne ograniczenia. Przestrzeń wewnątrz pałąka jest na tyle mała, że spięcie ramy roweru z elementami miejskiej infrastruktury bywa wyzwaniem.
W większości przypadków najwygodniejszym i najbardziej optymalnym rozwiązaniem, jakie stosuję, jest przełożenie u-locka przez tylne koło, wewnątrz tylnego trójkąta ramy. Zapięcie idealnie mieści się w tej przestrzeni. Oczywiście, w teorii ktoś mógłby wrzucić tak zabezpieczony rower do vana, jednak dla moich potrzeb – gdy zostawiam rower pod sklepem dosłownie na…

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