How to use

Wrap the chain around the bicycle frame and a fixed object such as a bike rack or pole, ensuring the frame and at least one wheel are secured where possible. Insert the chain ends into the keyed cylinder and turn the key to engage the lock. Remove the key and keep it in a safe place. When unlocking, insert the key, turn to release the mechanism and remove the chain. Regularly inspect the chain and cylinder for wear or damage and keep the lock dry to prevent corrosion.

Usage recommendations

For improved security, use the chain in combination with other locking methods (for example, a U-lock for the frame) and secure both the frame and one wheel when possible. Store the key in a dedicated place and check the cylinder periodically for dirt or moisture. Avoid leaving the locked bicycle in isolated areas for extended periods.
