Using this ULAC lock is a breeze. First, find a suitable place on your bike, like the top tube or seat post, to secure the lock. You can use the ULAC velcro to neatly store the chain when not in use. To open and close the lock, set your desired combination from the 10,000 unique options available. When transporting your bike, just wrap the chain around the top tube or seat post. As for maintenance, keep the lock clean and dry. Avoid exposing it to extreme heat or cold as this might affect the hardened steel chain and the combination lock mechanism. Also, if the nylon sleeve gets dirty, you can gently clean it with a damp cloth.
