One Lock. Two Diamond Ratings. Zero Compromises.
Delivering next-level theft protection for your motorcycle, scooter or bicycle, Oxford's Grinder range is engineered to combat the growing threat of angle grinder attacks.
Independently tested and awarded the highest grade Sold Secure DIAMOND ratings for both Powered Cycle and Pedal Cycle and backed by Oxford's long-term 10 year guarantee* the Grinder is security you can trust.
Engineered Beyond Attack.
Designed in house using the latest CAD technology…
Double Locking Mechanism
Double the attack time required
The high-security double-locking system prevents shackle rotation, meaning thieves must cut through both sides of the lock to gain access.
Anchoring the shackle in two places significantly increases resistance to leverage and twisting attacks and in the event of a partial breach, the lock body remains secured.
ANTI DISC CUTTER COATING
Science Backed Security
Grinder is 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.
