The OnGuard Pitbull Mini U-Lock delivers heavyweight security in a compact, commuter-friendly design. Featuring a 14 mm hardened steel shackle and the X4P Quad Locking Mechanism, it locks on all four sides for powerful resistance against prying, twisting, cutting, and leverage attacks. With its shorter 205 mm shackle size, the Pitbull Mini reduces usable space for thieves while still offering flexible locking options for bikes, e-bikes, scooters, or campus use. A rubber-coated crossbar protects bike finishes, and the included all-tube mounting bracket provides convenient transport. Comes with five laser-cut keys, including one micro-LED key for nighttime use.
