Maximum Anti-Theft Security: Folding Bicycle Lock Chain
Don’t leave your valuable bicycle vulnerable to theft. The CycleAddons bicycle lock chain introduces an engineered “Hamburg-style” folding structure that combines heavy-duty physical defense with unmatched portability. Crafted from ultra-durable zinc alloy with 3mm hardened steel plates, this lock folds tightly into a sleek, compact shell that stores neatly on your bike frame without rattling during your ride.
Why Cyclists Trust This Folding Chain Lock:
Engineered with 4 interconnected chain blocks reinforced with 3mm heat-treated hardened steel plates. The outer zinc alloy shell is wrapped in high-impact ABS resin to shield your bicycle’s paint job from scratches, chips, and wear.
Features an advanced anti-drill locking cylinder designed to defeat picking tools, power drills, and mechanical intrusion methods. Includes 3 precision-cut high-grade steel keys so you always have spares at home or work.
Unlike bulky U-locks or heavy traditional chains, this folding lock collapses smoothly into a burger-like puck shape. The quick-release mounting bracket easily attaches to your bicycle seat post or frame tubing for noise-free carrying.
