1. Concealed anti-theft design The concealed structure allows the lock body to be seamlessly embedded in the helmet or in the gap of the vehicle body, without an exposed lock hook, effectively preventing it from being pried or cut by tools, greatly improving anti-theft security. 2. 5-point fixed reinforcement system The original five-anchor locking technology (top + sides + front and back) disperses the force at multiple points, which not only prevents the helmet from shaking and falling off, but also avoids single-point violent damage. It is compatible with all types of helmets such as full-face helmets and half-face helmets. 3. Quick-release tool-free installation The accessories include a high-strength adhesive base and a screw fixing dual option. Users can complete the installation without professional tools, and it is suitable for motorcycle pipe beams, shelves and other parts. 4. Military-grade alloy material The lock core is made of C-grade anti-theft zinc alloy, and the lock hook is heat-treated manganese steel, which is resistant to hydraulic shearing, rust and corrosion, and has a load-bearing capacity of 50kg. It can be used stably in an environment of -30℃ to 80℃.
