Bike Chain Lock - Sold Secure Gold - 4ft with 4 Keys - Heavy Duty Bicycle, Ebike & Motorcycle Lock

The KOHLBURG security chain lock of the Helsinki type offers strong German security standards with a convenient length, prioritizing security without distracting with fancy designs or gimmicks. This lock features a chain with 4-edge links that protect against bolt cutters due to the larger diameter, made of hardened special steel to resist bolt cutters and metal saws.

The extra-long 4-foot chain allows flexible locking without much effort, even to wide objects like street lamps or trees. While no lock is entirely unbreakable, this chain lock provides the highest possible security for a conveniently portable option. The advantages include massive hardened special Titanium steel, a secure lock cylinder with car security standard, and a chain with 0.33-inch thick 4-edge links for the highest security level against bolt cutters and hacksaws.

Unlike many other chain locks advertised as lightweight, this KOHLBURG lock prioritizes security over weight reduction, using solid hardened steel instead of light steel with reduced safety. The tradeoff is a heavier lock weight of 5.5 lbs, but the company believes there is no shortcut for security. The extra-long 4-foot chain allows securely locking both the bike frame and front wheel, or multiple bikes at once, to a fixed object.

To protect the bike's varnish, the chain is coated with a soft and robust sleeve. The lock comes with 4 keys and is greatly suited for high-quality bicycles, e-bikes, and motorbikes. As the company states, "better massive than sorry" when it comes to bike security. This lock is designed to protect, not serve as a lifestyle accessory with exciting gimmicks.
