OnGuard Pitbull STD DT U-Lock with 4 ft Cable – 14 mm Hardened Steel Shackle (115 × 230 mm) – Quad Lock System for Bike Security – Rubber-Coated Finish, 5 Keys with LED & Mount Bracket

The OnGuard Pitbull STD DT U-Lock delivers layered bike security by combining a heavy-duty 14 mm (0.55 in) hardened steel U-lock with a flexible 4 ft vinyl-coated security cable. The X4P Quad Lock mechanism secures the shackle on four sides to resist cutting, prying, twisting, and leverage attacks in medium- to high-risk environments. The included cable allows riders to secure additional components such as wheels, seats, or accessories, creating a versatile double-locking system for bikes, e-bikes, and scooters. Rubber-coated shackle sleeves and a co-molded crossbar help protect frames from scratches. Includes five precision laser-cut keys, and a universal mounting bracket for convenient transport.
