Description

Serious security for your bicycle, electric bike or motorbike. The Oxford Grinder S1 260mm 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 260mm outer height offers a more compact fit around frames, wheels and close-fitting 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.
