How to use

Thread the chain through the frame and one wheel of the bicycle or around the item to be secured, then wrap it around a fixed, immovable object such as a bike rack or sturdy pole. Insert the chain end into the keyed cylinder and turn the key to lock. Keep the key in a secure place and consider carrying a spare key. When unlocking, insert the key and rotate to release the cylinder, then remove the chain and stow it for transport.
