The OnGuard Pitbull Mini U-Lock delivers high-security bike protection in a compact design ideal for commuters and urban riders. Built with a 14 mm (0.55 in) hardened steel shackle and the advanced X4P Quad Lock system, the lock secures on four sides to resist cutting, prying, twisting, and leverage attacks. Its compact interior dimensions of 90 mm × 140 mm (3.55 in × 5.52 in) minimize leverage space while still allowing flexible locking around racks, posts, and bike frames. A rubber-coated crossbar and protective shackle sleeves help prevent scratches on bike finishes and components. Includes five precision laser-cut keys, and a universal mounting bracket for convenient on-bike transport.
