Key specifications

• Lock type: keyed chain lock with integrated cylinder
• Chain construction: hardened metal links with protective cover
• Form factor: compact, portable chain-and-lock unit for everyday carry
• Intended use: securing frames and wheels to fixed objects for short- to medium-term parking
• Suitable transports: bicycles, scooters and similar personal mobility devices

How to use

Pass the chain around a secure fixed object and through the bicycle frame or wheel, then insert the chain end into the lock body and turn the key to engage the cylinder. Ensure the chain is threaded so that the lock sits close to the frame or rack, reducing leverage points for cutting tools. Keep the key in a safe place and carry a spare key if frequent locking is expected. Regularly inspect the chain and lock body for signs of wear or corrosion and lubricate the cylinder occasionally according to standard mechanical lock care.

Usage recommendations

For improved security, lock both the frame and one wheel to a fixed object and choose well-lit, supervised parking locations. Avoid leaving the lock exposed to prolonged moisture; store the lock in a dry place when not in use and clean and lubricate the cylinder periodically to maintain reliable operation.
