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."

X3 Ultimate Urban Bundle
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-lock 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 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 d-locks whereas X3 has at least 20 times the resistance.
What is the locking circumference of LITELOK X3?
LITELOK X1 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.

Nothing is Thief proof, but I reckon the X3 is as close as you can get, fits the front wheel on my Himalayan 450 with a bit of room to spare allowing me to run my ground anchor chain through it when parked up. The X3 is slightly too small to go over the rear wheel.
I added the RBF tag as I'm old and forgetful, attempting to ride the motorcycle would not end well for the bike or rider!
Expensive but what price security?

As per the product description this weighs 2.1kg so keep this in mind if you're going to be cycling for any greater distances and presumably carrying this with you. I can't realistically expect any opportunist theft to even bother trying to break this lock as its appearance alone makes a statement of "f*%k off!". The lock is expensive however it cost over £12k to replace my bike with a brand new one. The key mechanism can be slightly awkward to open sometimes. Some cyclist may prefer to go with the X1 which is slightly lighter but offers less resistance to thieves.

I have absolute confidence in the lock, my only worry was whether I could fit it on my speed RX.
Plenty of photos of the lock fitted to street triples, a couple of it fitted to speed 1050s but non of it fitted to a speed 1200. Bit of a leap of faith.
But it does, so it worked.
I bought a bundle (2x 'x3's) could really do with litelok producing a link piece like their rivals to tie two bike together with the same grinder resistance as the lock. As they say" the chain is only as strong as the weakest link".

I bought a Kryptonite NY Diamond at first but it came with a chipped keyhole cover and the shackle had more slack than I’d like. Ended up returning it.
This lock definitely feels solid. The only reasons I didn’t give it full stars is, price increased recently and it’s already expensive and doesn’t come with a holder. The other reason is, the silicone like coating on the shackle is slowly rubbing off onto my handlebar. That’s how I carry the lock, also incase I have to defend myself it’s handy as a Baronium Knuckle. Just worried it will wear a hole in the coating.
