Abus Insert Chain ACH Classic 5KS/150 Black

Unmatched Security Meets Effortless Convenience for Your E-Bike.

Protecting your e-bike from theft demands more than just a lock—it requires a smart, versatile solution. The Abus Insteekketting ACH Classic 5KS/150 black delivers double-layered security by combining a hardened steel insert chain with a sleek, newly designed oval Loop-Ring. Its slim profile allows you to thread the chain easily through spokes and narrow gaps, making locking up faster and more efficient. Integrated with a ringslot that blocks your rear wheel, this system prevents wheel theft while enabling you to secure your bike to fixed objects like lampposts or bike racks. No extra keys needed—one key controls both lock and chain, wrapped in a protective textile sleeve to guard your bike’s finish. Elevate your e-mobility security with a solution engineered for urban riders who demand strength, style, and simplicity.
