## Features

- Upgrade --- This Upgrade Series has improved the digital dials by transitioning from PVC to metal material, removing previous weaknesses and significantly improving the overall security of the bike chain lock. The length remains at 3.2 feet, with a weight of approximately 1.65 pounds
- 5-Digit Combination --- Our bike chain lock provides heightened security with its 5-digit combination lock design. With over 100,000 possible combinations, it surpasses the standard 4-digit locks in terms of safety and convenience
- Resetting is Simple --- The default password is "00000". To set a new password, just rotate the knob 90° to input your desired code, then move back the knob to its initial position. Your new password is now ready for use to unlock the lock
- Sturdy & Durable --- This bicycle lock is made from a 0.24 inch/6 mm thick alloy steel chain and a strong zinc alloy lock core that resists cutting and sawing. The fabric and PE cover protect the lock chain and core from rainwater and sand, enhancing durability
- Wide Application --- This bike lock chain is sufficiently long to secure 2-3 bikes together or attach your bike to a tree, gate, fence, rail, or pole. Additionally, the chain lock can be utilized for motorcycles, electric scooters, ebikes, skateboards, grills, ladders, doors, lawnmowers, and more
