INTEKIN motorcycle and bicycle chain lock, Black, 8mm square links, 3.3FT with 16mm U-lock and PVC sleeve

This heavy-duty chain lock pairs a heat-treated manganese-steel square-link chain with a rugged U-lock and a precision zinc-alloy cylinder to protect motorcycles, bicycles, gates, ladders, and outdoor equipment. Designed for visible deterrence and cut resistance, the INTEKIN chain brings a balance of strength, weather protection, and convenient handling for daily use or longer-term parking.

How strong is the chain and what materials keep it secure?

The chain uses 8 mm heat-treated manganese steel square links engineered to resist cutting, sawing, and shearing. The U-lock body is made from thick carbon-structural steel and includes a PVC-covered shackle for added cutting resistance and corrosion protection.

• 8 mm (0.32 in) heat-treated manganese-steel square links
• 0.64 in carbon-structural steel U-lock (including 0.1 in PVC cover)
• Precision zinc-alloy blade lock cylinder with dust cover for anti-tamper protection
• 16 mm U-lock included for anchoring and added rigidity

Will the lock hold up outdoors and avoid jamming?

The cylinder features a zinc-alloy blade design plus a dust cover and copper components to reduce the chance of corrosion and jamming. A PVC sleeve around the chain helps keep dirt and moisture away from metal surfaces, extending service life and preventing scratches to your vehicle.

• Cooper lock cylinder and dust cover minimize moisture ingress
• PVC protective sleeve reduces rust and prevents paint damage
• Corrosion-resistant materials suited for outdoor storage

How practical is it for everyday use and transport?

At 3.3 feet (100 cm) long and about 4.2 lbs in weight, the chain finds a middle ground between portability and security. It comes with three copper keys, so you have spares, and the flexible sleeve keeps it from scratching your bike while you carry or wrap it around an anchor point.

• 100 cm (3.3 ft) total length including double loop ends for versatile anchoring
• Weight: approximately 4.2 lbs for increased resistance to attacks
• Three copper keys included for backup access
• Flexible cloth sleeve resists abrasions and protects finishes
