The OnGuard Pitbull Mini LS U-Lock delivers professional-grade protection with extended reach and unbeatable durability. Its 14 mm hardened steel shackle resists cutting, sawing, and prying while the X4P Quad Lock mechanism secures on all four sides for total strength. The advanced Z-Cylinder core blocks picking and drilling attempts, and the co-molded crossbar cover prevents scratches on your bike’s finish. Designed with a TriRadius frame for extra clearance, it fits urban, commuter, and e-bikes. Includes five laser-cut keys (one with LED) and a convenient mounting bracket for storage.
