Built for maximum everyday security, the OnGuard Pitbull STD DT U-Lock combines a strong 295 mm hardened steel shackle with the X4P Quad Locking Mechanism for powerful, four-sided protection against twisting, cutting, and leverage attacks. The included 4-foot vinyl-coated cable adds an extra layer of protection by securing wheels, seats, or accessories, making this the ideal double-team locking system for bikes, e-bikes, and scooters in medium- to high-risk areas. A rubber-coated crossbar protects your bike’s finish, and the universal bracket provides easy on-frame transport. Includes five laser-cut keys—one with LED for nighttime access.
