As Good As It Gets
Had my old bicycle stolen with a U-lock from a popular company within seconds. After doing some research I ended up purchasing the X3 for my new ebike. Love this thing. Heavy duty and gives me piece of mind when locking it up outside. It also comes with a pouch I use before storing it in my pannier bag. Highly recommend and worth the investment in my opinion.

Peace of mind
Strong, well made, and feels good in my hands! Don’t scratch the paint in my bike rims. But most importantly, I have the certainty that I can keep my eyes off my bike with this lock. Litelok X3 is superior to any other lock, that’s a fact!

Solid as an Abrams tank
UK quality. Unpickable Abloy lock. You need a torch to cut this baby. Angle grinder takes too long. It’s heavy but comes with a wet suit material bag so it’s easy to strap down with bungie cords. I purchased 2. Great investment to secure my E-bikes.

What the experts say...
John Milbank, Bennetts BikeSocial
"By having the Litelok X3 as part of that set-up, you’ve made your bike one of the hardest to steal on the street. The Litelok X3 is now my personal choice of portable lock, and very much worthy of a BikeSocial recommendation."
Carl Ellis, thebestbikelock.com
"The Litelok X3 is the most angle grinder resistant portable bike lock I’ve ever tested. And I’ve tested them all now, so that means it’s the most angle grinder resistant portable bike lock you can buy!"
Ben Clarke, Motorcycle News
"X3 Moto has achieved a Sold Secure Diamond rating for bicycle and motorbike applications. And for an added bonus, it’s made in Britain at a solar-powered factory."

LITELOK X3
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 X3 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 X3 is at least 20 times more angle grinder resistant than the current leading D-locks as well as needing multiple discs and batteries to cut it.
How much does LITELOK X3 weigh?
LITELOK X3 weighs approximately 2.1kgs or 4.6lbs.
What's the difference between X3 Bike and X3 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 X3 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.
How do I carry LITELOK X3 on my bike?
If you'd like to carry LITELOK X3 on your bike, you'll need to purchase the X3 Tactical Mount - a tough mount for the world's toughest lock.
What is the locking circumference of LITELOK X3?
LITELOK X3 has a full-sized locking circumference of approximately 100 x 195mm.
Has LITELOK X3 been independently tested?
Yes, it has been thoroughly tested by Sold Secure and both locks achieve Sold Secure Powered Cycle and Pedal Cycle Diamond levels (the highest ratings available). It has also been tested by ART, and certified 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 X3 made from?
LITELOK X3 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 X3 is sold with a 7-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.

Fantastic lock, the pouch is also a great idea to slip it into for commutes, I’ve had motorcycles stolen in the past despite having locks and chains on that were too easily cut through, so this product really has given me a peace of mind that is invaluable.
£250 investment is peanuts really to protect your bike.

It looks solid and very hard to break. The rubberised outer layer is particularly useful considering that I put the lock in the front wheel of my GSA. Insurance company hasn’t really considered too much the lock for covering purposes. It is heavy to carry and I have to store it in the back top case. When I ordered the lock I had a discrepancy for the address and Ben has assisted me all the way through. I believe this is a typical example on how to go for the extra mile. Well done! I am definitively happy with the purchase.

After extensive reviews online and watching multiple videos on angle grinders cutting through locks in seconds and how quickly a lock can be defeated, I was on a quest to find the best lock, period. My daughter is attending college in California on a campus that sees thefts of scooters, bikes and skateboards every single day. My daughter's friend had her locked scooter stolen in under 30 seconds. The dorms reviewed the security camera footage and watched a thief casually walk up to the scooter, pull out a bolt cutter and ride away with the scooter. I knew I needed the best lock I could find.
The LITELOK is that lock! My daughter has been locking her scooter outside at her dormitory when others have been bringing their scooters into their rooms. Several students have commented that they can't believe her scooter wasn't stolen. Kids are asking her what brand of lock she has and where can they get it? Everyone is so surprised at the quality and safety features of the lock. If you need an outstanding lock that will truly protect your bike or scooter, look no further, this is the lock to get!

I toiled with the idea of getting a cheaper lock, but after watching countless bike lock reviews/tests on YouTube, I took the plunge and went for the X3. I'm so glad I did. It's tough and definitely heavy duty, but the coating isn't abrasive on my brand new Cube Stereo hybrid one44 AT. I sleep better knowing this lock is on my bike. I'm so impressed with the lock, I'm going to get the X1 and Core flex to link my bike to a wall anchor when home and have options when I'm out and about.

After several research on the web watching test videos, it seems quite obvious that the Litelok X3 should be the strongest lock out there. I got some of the best KRYPTONITE U lock, but the LITELOK X3 is another level above. The construction is phenomenal, it feels massively sturdy, and after seeing the test videos, I feel very confident leaving my bike to go shopping and else, I love it and would feel as safe with anything else.
Thank you for taking the time and energy to produce such a beast !
