The OnGuard Brute Mini U-Lock sets a new benchmark for compact, high-security protection, engineered to safeguard bikes, scooters, and e-bikes in high-risk areas. Its 16.8 mm hardened steel shackle is fortified with the X4P Quad Lock system, which secures on four sides to resist twisting, prying, and cutting. Designed for both durability and practicality, the Brute Mini features a protective rubber coating to shield paint finishes and a co-molded crossbar cover that prevents damage during daily use. The compact 205 mm × 170 mm × 50 mm frame fits neatly into messenger bags or backpacks, making it ideal for commuters and couriers. With five precision-cut keys (one LED for night use) and an all-tube mounting bracket, this U-lock delivers professional-grade protection in a portable, easy-to-carry design.
