Litelok U-lock

British lock maker Litelok has been working on high-security bike locks for a few years now, and this is its latest piece of kit.

The X1 Moto U-lock claims to offer ‘unparalleled’ resistance to angle grinder attack, thanks to a composite steel/ceramic construction with layers of super-hard ‘Barronium’ material (named after the firm’s founder, Professor Neil Barron), bonded with high grade steel. The composite material gives angle grinders a torrid time, wearing out discs and batteries faster than normal steel locks. It’s Sold Secure Diamond rated, so has passed some pretty tough tests, and the top-spec X3 version uses an ABLOY Sentry lock cylinder. Made in the UK, it also features a soft rubber outer sleeve to protect your bike and weighs in at 1.7-1.9kg.

£149.99 (X1), £249.99 (X3)
