ARMOURED BIKE LOCKS
The LITELOK X range is armoured with our patent pending Barronium®, a highly advanced and super hard ceramic composite material that is tougher than the grinder discs themselves. It repels angle grinder attacks by turning the grinder's energy and force in on itself.
Continuous cutting wears down the grinder discs, batteries and ultimately the grinder motor itself. This gives LITELOK X up to 20 times more resistance than the current best-selling D-locks.
Barronium® is permanently fused to a hardened fine-grain high-tensile steel core which provides protection against all other commonly used tools such as bolt croppers, cable cutters, long bars, hammers and chisels. A unique anti-rotation feature protects against twisting attacks and single cuts. Accredited to Sold Secure Bicycle and Motorcycle Diamond level, LITELOK X locks will protect your bike against even the most determined bike thieves.

"The Litelok X strikes a formidable balance between cost and performance. This is going to stop a thief cutting through it in any kind of reasonable time, and they’ll most likely move onto something else."
