I keep the bike stored in our three car garage which has alley access. I didn't ride it for a few days, and then walked in and poof! Bike gone. I store it hanging from the ceiling on the inside wall of the garage, in front of all the vehicles so maybe someone walked by and snatched it if the door was open momentarily and a vehicle was out so there was a clear line of sight? It's not locked when it is being stored/hung, the Abdus lock is stored on the bike itself. Someone removed my helmet, threw it on the floor, and took the bike. The bike had a black and red Abdus lock, as well as a mini pump - both attached.
