1100mm Heavy Duty Keyless Security Chain Lock

Product Overview

Secure your ride with premium, keyless protection. This heavy-duty chain lock is engineered to deliver elite-level defence without the hassle of carrying keys. Constructed with 9mm square links made from specially hardened steel, it provides exceptional resistance against aggressive theft attempts, including cutting, sawing, and shearing.

The lock features a fully enclosed, reinforced lock head design that deflects impact tools, while a thick, soft EVA fabric coating wraps the entire chain length to safeguard your frame's paintwork from scratches. At 1100mm, it offers the perfect balance between portable weight and ample length for securing your frame and wheel to fixed structures.

Key Features

• 9mm Hardened Steel Square Links

  Built with 9mm square-profile links that resist heavy-duty bolt cutters and hacksaws. The square shape presents flat surfaces that deflect cutting edges far better than traditional round chains.

  The heavy-duty locking mechanism is housed within a fully enclosed structure, providing a high-strength shield that resists brute-force thumping, hammering, and prying.

• Keyless Combination Entry

  Equipped with a secure code mechanism, eliminating the risk of lost keys or jammed keyways. Set your own combination for fast, seamless access on every ride.

• Paint-Safe EVA Protective Sleeve

  Wrapped in a thick, durable, and soft EVA material coating that absorbs impacts and prevents metal-on-metal contact, keeping your frame immaculate.

• Elite 6-Star Security Rating

  Rated at a maximum security level (6/6 Stars) to deliver professional-grade protection for high-value bicycles and e-bikes in urban environments.
