Heavy-Duty 10mm Hardened Steel Chain The Mastiff's 10mm chain is built to resist bolt cutters, hacksaws, and leverage attacks. Whether you're locking up at a transit station, parking garage, or city street, this chain provides the robust protection your e-bike deserves.

110cm Length — Versatile Locking Options At 110cm, the Mastiff gives you enough reach to secure your frame and wheel to a wide range of fixed objects — bike racks, poles, fences, and more. Ideal for urban commuters and e-bike owners who need flexible, reliable locking solutions.

Integrated Lock for Streamlined Security The built-in lock mechanism eliminates the need for a separate padlock, keeping your setup clean and reducing the number of components to carry. Designed for quick, one-handed locking and unlocking.
