Description
The Oxford Grinder Shackle U-Lock is a high-security bike lock and motorcycle lock engineered to resist angle grinder attacks, providing exceptional protection against modern theft methods. 

The Oxford Grinder range is engineered to combat the growing threat of angle grinder attacks, delivering next-level security for your bike.

Independently tested and awarded Sold Secure Diamond certification for both bicycles and motorcycles, it features a hardened steel shackle and advanced locking mechanism, this premium U-lock delivers trusted bike and motorcycle security for riders who demand security at home, at work, and on the move.

Both the Grinder S1 and S2 are designed to outlast and outperform leading locks, resisting up to 5x more cutting discs thanks to their hardened square steel shackles and advanced anti-angle grinder carbide coating. The unique faceted carbide surface deflects grinder blades from edge to edge, rapidly destroying discs and dramatically slowing down theft attempts.

A high-security double-locking system prevents shackle rotation, meaning thieves must cut through both sides of the lock to gain access.

Certified Powered Cycle and Pedal Cycle Sold Secure DIAMOND this security solution is the last lock you’ll ever need.
