Use the provided key to unlock the U-lock. To secure the bike properly, pass the shackle around the frame of the bike before securing it to a bike rack or pole. Once the frame and pole are all positioned within the shackle, reattach the locking mechanism and secure it with the key. Always activate the alarm with the provided key fob whenever the bike is locked up. When possible, bring the bike inside and we recommend never leaving it locked outside over night.
