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.
The world's first long reach grinder resistant lock
Building on the award-winning performance of the LITELOK X1, the new X1 PLUS takes security and versatility to the next level.
At 60mm longer than the standard X1, it’s the ultimate combination of strength, practicality, and versatility.

Frequently Asked Questions
Can the LITELOK X1 or X1 PLUS be cut with an angle grinder?
Unfortunately, all locks can be cut with the right tools and enough time. The time required depends on factors such as the power of the angle grinder, the cutting discs used, and the skill of the user.
During our own testing and independent testing, we found that both the LITELOK X1 and X1 PLUS are at least 5 times more resistant to angle-grinder attacks than current leading D‑locks, requiring multiple cutting discs to make a successful cut. This significantly increases the time, effort, and noise involved, acting as a strong deterrent in urban and higher‑risk environments.
What’s the difference between the LITELOK X1 and the LITELOK X1 PLUS?
Both the LITELOK X1 and X1 PLUS use patented Barronium® angle-grinder‑resistant armor and deliver the same level of core security. The key difference is their size and internal reach.
- LITELOK X1 offers a strong balance of security, weight, and everyday practicality, making it well suited for standard urban locking scenarios.
- LITELOK X1 PLUS features an extended internal locking length, providing additional reach for larger frames, thicker bike stands, awkward street furniture, or locking multiple bikes together.
The X1 PLUS is designed for situations where extra reach is needed, while the X1 provides a lighter, more compact option for everyday use.
Why does this bundle include two different LITELOK locks?
This bundle is designed to provide maximum locking flexibility.
Use the X1 PLUS when you need additional reach for challenging locking points and use the X1 when a lighter, more compact lock is more practical. Together, they allow you to double-lock your bike, secure different components, or daisy‑chain around larger or awkward street furniture in busy urban environments.
What is the locking circumference of the LITELOK X1 and X1 PLUS?
- LITELOK X1 has an internal locking space of approximately 101 × 197 mm / 3.97 × 7.7", offering a versatile balance of reach and portability.
- LITELOK X1 PLUS has an extended internal locking space of approximately 101 × 255 mm / 3.97 × 10", giving significantly more reach for demanding locking situations.
The difference in internal length makes the X1 PLUS better suited to larger frames and thicker stands, while the X1 remains more compact and easier to manage day‑to‑day.
Can I attach the X1 or X1 PLUS to my bike?
Yes. Both the LITELOK X1 and X1 PLUS can be attached to your bike using the X1 Tactical Mount (sold separately).
The X1 Tactical Mount is designed to securely hold the lock on your bike frame during everyday riding, keeping it stable even on rough roads.
Each mount carries one lock — if you wish to mount both locks simultaneously, two separate Tactical Mounts are required.
All mounts and carrying accessories are sold separately unless otherwise stated.
Is this bundle suitable for urban and higher‑risk areas?
Yes. This bundle is designed specifically for urban and higher‑risk locking environments.
Both the LITELOK X1 and X1 PLUS are independently tested and certified Sold Secure Bicycle Diamond and Powered Cycle Diamond, as well as ART4, making them suitable for bikes, e-bikes and motorcycles where a strong physical and visual deterrent is essential.
Have the LITELOK X1 and X1 PLUS been independently tested?
Yes. Both locks have been independently tested by recognised testing bodies including Sold Secure and ART.
Sold Secure testing is owned and administered by the Master Locksmiths Association, with evaluations carried out in purpose-built laboratories in the UK. Both the LITELOK X1 and X1 PLUS achieve Sold Secure Bicycle Diamond and Powered Cycle Diamond certification, the highest levels available under the Sold Secure rating system.
Both locks are also certified ART4, confirming their resistance against sustained and professional‑grade attack methods.
These certifications provide independent assurance that both locks meet stringent real‑world security standards for urban and higher‑risk environments.
What are the LITELOK X1 and X1 PLUS made from?
The LITELOK X‑range is built with Barronium®, a patented anti-angle-grinder composite material that is permanently fused as armor to provide exceptional cut resistance. The Barronium® layer is specifically engineered to repel and degrade angle-grinder cutting discs, significantly slowing modern theft attacks.
The X‑range uses a three-layer construction:
- A fine-grain, hardened high‑tensile steel core, providing strength against twisting, leverage, and multiple tool attacks
- Patented Barronium® composite armor, permanently fused to the steel core to resist angle-grinder cutting discs
- A plant‑based eco-rubber outer layer, soft to the touch to help protect your bike frame from damage
Both the X1 and X1 PLUS use the same materials and construction, with differences focused on size and reach rather than security performance.
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’s the difference between LITELOK X Bike and X Moto versions?
There is no physical or technical difference between the Bike and Moto versions of LITELOK X‑range locks — including the X1 and X1 PLUS. They are exactly the same locks, using the same materials, construction and security technologies.
The Bike and Moto naming is used solely to help riders understand how a lock can be applied across different use cases, such as bicycles, e-bikes and motorcycles. The lock itself remains unchanged, only the intended application.
What is the warranty on this bundle?
Both the LITELOK X1 and X1 PLUS are covered by a 3‑year warranty, covering mechanical or operational faults arising from normal use.
Cosmetic wear and tear is not covered. Registering your lock and keys allows replacement keys to be ordered if required.
