Description

Serious security for your bicycle, electric bike or motorbike. The Oxford Grinder S1 320mm U-Lock is engineered to resist angle-grinder attacks, pairing a 14mm hardened-steel shackle core with a specialist anti-disc-cutter carbide coating. Its double-locking design secures both ends of the shackle, while the 320mm outer height offers extra reach around larger frames, railings and ground or wall anchors.

Why choose the Oxford Grinder S1?

  • Sold Secure Diamond: independently certified to both Pedal Cycle Diamond and Powered Cycle Diamond.
  • Anti-angle-grinder protection: Oxford states its carbide coating takes an average of 10 cutting discs to cut through one side under its test conditions; real-world results vary.
  • 14mm hardened-steel shackle: robust square-section core with a protective silicone covering to help prevent scratches.
  • Double-locking mechanism: prevents shackle rotation and requires both sides to be cut to fully remove the lock.
  • Weather-ready details: self-sealing keyway cover helps keep out water and debris.
  • High-security cylinder: disc-detainer mechanism designed to resist picking and drilling.
  • Everyday convenience: supplied with three keys and a carry bracket; Oxford replacement-key service available.
