Heavy Duty 4ft Bike Chain Lock with 4 Keys

SECURITY FIRST, NO EXCUSE GIMMICKS This Helsinki-type chain lock is designed to protect high-quality bikes and motorbikes, focusing solely on security. Unlike other locks that may include gimmicks, we prioritize robust design and top-tier security by using especially strong Titanium steel and a safe cylinder that meets car security standards.

SOLID STEEL INSTEAD OF LIGHT STEEL Unlike many other chain locks that offer lightweight options, we use solid hardened steel, ensuring unparalleled security against bolt cutters and metal saws. Although this results in a weight of 5.5 lbs, the high anti-theft focus is well worth it for motorcycle scooters, mopeds, ebikes, and bike trailers.

EXTRA-LONG LOCK The Helsinki chain lock boasts an extra-long length of 4 feet (47 inches/120 cm). This extended length provides maximum convenience and security by allowing you to lock both your bike frame and the front wheel to a fixed object, or secure multiple bikes at once.

HIGH SECURITY CHAIN The chain features strong 0.33" (8.3 mm) 4-edge links, providing a high level of security against bolt cutters and hacksaws. The lockhead is equipped with an anti-lock-picking cylinder, making it extremely difficult for thieves to pick the lock. Additionally, the chain is coated with a soft, robust sleeve to protect your bike’s varnish. The lock also comes with 4 keys.

BETTER MASSIVE THAN SORRY While locks with smaller chain diameters are lighter, they offer minimal protection. Conversely, this chain lock prioritizes security, even if it means carrying a slightly heavier lock. However, as we like to say, "Better massive than sorry." If you value security over weight, this Helsinki chain lock is the perfect choice for your high-quality bike or motorcycle.
