ROCKBROS 22mm Heavy-Duty Alloy Steel U-Lock — Cut-Resistant Anti-Theft Bike & Motorcycle Lock
Product Description The ROCKBROS 22mm heavy-duty alloy steel U-lock is engineered for riders and vehicle owners who demand high security. The shackle is made from high-strength alloy steel and processed with vacuum heat treatment to significantly increase hardness, effectively resisting hydraulic cutters, hammering, and power saw attacks. The 22mm reinforced diameter provides a strong advantage over comparable products, offering reliable protection for bicycles, electric bikes, motorcycles, and even garden gates. The lock is fully wrapped in a silicone protective sleeve that prevents freezing and cracking while protecting the frame or paintwork from scratches. The cylinder is a precision zinc-alloy lock core with anti-drill, anti-pry, and anti-manipulation features; the key operates smoothly and is highly durable. A vehicle-mounted bracket is included for easy carrying during rides, so security travels with you. Whether for urban commuting, off-road riding, or long outdoor parking, this U-lock gives you tangible, dependable protection.
