The model integrates a spiral steel cable coated with a vinyl layer, which effectively prevents cutting attempts and protects the bike frame from scratches.

X2P and Z-Cylinder Security Technologies

The OnGuard Doberman features a locking mechanism based on X2P - Double Bolt technology, which means it has a double shackle that ensures stability and resistance to tampering.
