Heavy Duty Anti-Theft Bike Chain Lock

Security & Convenience: With a combination of five and a half password rounds, this lock offers over 1,000,000 password combinations, including a hidden round between the upper and lower numbers, making it more secure than a standard five-password lock. Setting a password is easy, eliminating the need to carry a key.

Strong & Durable: The chain is constructed from 6mm solid alloy steel, with sealed welding connections for added strength and durability. The built-in zinc alloy lock core and coarse zinc alloy lock provide advanced anti-theft performance, resistant to smashing and skidding, and rust-resistant.

Anti-Wear & Sustainable: The high-quality polyester cloth wrap on the chain lock is scratch-resistant and protective of bike paint. It can withstand extreme weather conditions, providing protection from hot and cold temperatures. The cloth cover also extends the chain's service life compared to ordinary chains.

Versatile: This 3.2-foot long chain lock is suitable for securing 2-3 bikes together or locking a bike to various objects such as trees, gates, fences, railings, and thick poles. It can also be used for motorcycles, scooters, skateboards, grills, ladders, doors, lawnmowers, and more.

Note: Ensure the number wheel is in the correct unlocking password state before turning the reset disk when setting a new password.
