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.

LITELOK X3 weighs approximately 2.1kgs or 4.6lbs.

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.

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.

LITELOK X3 has a full-sized locking circumference of approximately 100 x 195mm.

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.

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.

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.

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.

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.
