OnGuard Brute Mini U Lock 90 X 140MM

The OnGuard Brute Mini U-Lock delivers elite-level protection in a compact format designed for bikes, scooters, and e-bikes in high-risk urban environments. Built with a massive 16.8 mm (0.66 in) hardened steel shackle and the advanced X4P Quad Lock system, the lock secures on four sides to resist cutting, twisting, prying, and leverage attacks. Its compact 90 mm × 140 mm interior dimensions provide tight locking around frames and racks, reducing leverage opportunities while remaining portable for commuters and couriers. A rubber-coated shackle and co-molded crossbar help protect bike finishes from scratches and corrosion. Includes five precision laser-cut keys, and a universal mounting bracket for convenient on-bike transport.
