Ultimate City Bundle - X3 and X1

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 used, the cutting discs, and the skill of the user.

During our own testing and independent testing, we found that the LITELOK X1 is at least 5 times more resistant, and the LITELOK X3 is at least 20 times more resistant to angle-grinder attacks than current leading D‑locks. The X3 also requires multiple cutting discs and batteries to make a successful cut.

This significantly increases the time, effort, and noise involved, acting as a strong deterrent—particularly in higher‑risk environments.

Both the LITELOK X1 and LITELOK X3 use patented Barronium® armor and are designed to resist modern theft methods such as angle-grinder attacks, but they are built for different levels of security demand.

• LITELOK X1 offers a strong balance of security and portability. It provides high resistance to angle-grinder attacks in a lighter, more compact format, making it well suited to everyday urban riding and regular locking scenarios.
  
• LITELOK X3 is LITELOK’s flagship lock, engineered for maximum resistance in higher‑risk environments. It incorporates additional Barronium® material, a thicker overall construction, and an ABLOY® SENTRY lock cylinder — one of the most pick‑resistant mechanical lock cylinders available. This greatly increases protection against sophisticated picking and manipulation attacks, alongside enhanced resistance to cutting attacks.
  

In short, the X1 delivers highly effective everyday security, while the X3 is built for riders who want the highest possible level of deterrence when locking in riskier locations.

This bundle is designed to deliver layered, adaptable security by combining maximum strength with everyday versatility.

Use the LITELOK X3 as your primary lock to secure the bike frame to fixed objects in higher‑risk environments. As LITELOK’s flagship lock, the X3 provides the highest level of deterrence against cutting and picking attacks.

The LITELOK X1 complements this by offering a lighter, more flexible option for securing additional contact points such as wheels, accessories, or a second bike.

The two locks can also be used together for daisy‑chaining, allowing you to extend your locking reach around larger or awkward street furniture, or to secure multiple bikes in one location. Used this way, the X3 delivers core strength while the X1 adds reach and adaptability.

Together, the bundle allows you to double-lock, daisy‑chain, and adapt to a wide range of real‑world parking scenarios — from everyday urban stops to higher‑risk locations where additional deterrence is essential.

• LITELOK X1 has an internal locking space of approximately 101 × 197 mm / 3.97 × 7.7", offering a strong balance of reach and portability for everyday locking, wheel security, and secondary locking points.
  
• 
  LITELOK X3 has an internal locking space of approximately 99 × 195 mm / 3.89 × 7.67", combined with a significantly thicker, heavier, and more reinforced construction. While its internal height is slightly shorter than the X1, the X3 delivers far greater overall strength and deterrence for securing larger frames, thicker street furniture, and high‑risk urban locking scenarios.
  

In this bundle, the X3 serves as the primary, maximum‑security lock, while the X1 adds reach and flexibility for secondary locking or daisy‑chaining where needed.

Yes. Both the LITELOK X1 and LITELOK X3 can be attached to your bike, using lock‑specific Tactical Mounts designed for their size and weight.

• LITELOK X1 is compatible with the X1 Tactical Mount (sold separately). This mount allows the lock to be securely attached to your bike frame for everyday riding and is designed to keep the lock stable, even on rough roads.
  
• LITELOK X3 is compatible with the X3 Tactical Mount (sold separately). This heavy‑duty mount is purpose-built for LITELOK’s flagship lock and holds the X3 securely on the frame, even over uneven terrain.
  

Please note that Tactical Mounts are model‑specific — the X1 Tactical Mount and X3 Tactical Mount are not interchangeable. All mounts and carrying accessories are sold separately unless otherwise stated.

Yes. The Ultimate City Bundle is specifically designed for urban and higher‑risk locking environments.

The LITELOK X3, our flagship lock, provides maximum deterrence in city settings where theft risk is highest. It combines patented Barronium® armor with a thickened construction and an ABLOY® SENTRY lock cylinder, delivering exceptional resistance to cutting, picking, and manipulation attacks.

The LITELOK X1 complements this by offering strong, angle-grinder‑resistant secondary security for additional locking points, such as wheels, accessories, or daisy‑chaining in crowded urban spaces.

Both locks are independently tested and certified Sold Secure Bicycle Diamond and Powered Cycle Diamond, as well as ART4, making this bundle suitable for bikes, e-bikes and motorcycles in city environments where a strong physical and visual deterrent is essential.

Yes. Both the LITELOK X1 and LITELOK X3 have been independently tested and certified by recognised security testing bodies, including Sold Secure and ART.

• Both locks achieve Sold Secure Bicycle Diamond and Powered Cycle Diamond, the highest levels available under the Sold Secure rating system.
• Both are also certified ART4, demonstrating resistance against sustained, professional‑grade attack methods.

Sold Secure testing is owned and administered by the Master Locksmiths Association, with evaluation carried out in purpose-built laboratories in the UK. These certifications confirm that both locks meet stringent standards for real‑world security performance in high‑risk environments.

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.

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 X3 use this proven construction, but the LITELOK X3 incorporates additional Barronium® material, a thicker overall profile, and structural reinforcement, making it LITELOK’s most secure and most resistant lock in the range.

There is no physical or technical difference between the Bike and Moto versions of LITELOK X‑range locks — including the X1 and X3. 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.

Warranty is applied individually to each lock included in the bundle:

• LITELOK X1 is covered by a 3‑year warranty
• LITELOK X3 is covered by a 7‑year warranty

Both warranties cover mechanical or operational faults arising from normal use. Cosmetic wear and tear is not covered. We recommend registering your locks and keys so replacement keys can be ordered if required.
