Using this U-lock is easy. First, find a suitable and sturdy object to lock your bike to. Insert the shackle through the bike frame and the object, then lock it with the key. Remember to keep the key in a safe place so you don't lose it. When it comes to maintenance, try to keep the lock dry. If it gets wet, dry it off as soon as possible to prevent rusting. Also, from time to time, you can apply a little bit of lubricant to the keyhole to make sure the key turns smoothly. Avoid using excessive force when locking or unlocking to prevent damage to the lock. This lock is designed to resist picking, drilling, twist attacks, bolt cutters, and leverage attacks, but don't expose it to extreme forces or tools that are specifically designed to break locks. Keep it in a normal environment to ensure its long - term performance.
