Like many have said here, I initially considered the "U" lock, and thought it would be handy in the stock storage area under the seat. However, I came to the conclusion that the U lock would really only be of benefit if it was long enough to lock the frame of the bike to an immovable object like a sign post, which it is not. I ended up with two small disc locks that store in the in the plastic tray over the battery, under the seat, quite nicely. I agree with Guth that a reminder is needed to go with disc locks. Instead of the cumbersome coiled reminder stretch cord, I found embroidered red & white "Remove Before Flight" cloth key fob tags on EBay for a couple of bucks. I then replaced the metal split key ring, with a heavy rubber band through the eyelet on the end of the tag. Now when I use the disc locks, the rubber band loops over one of my mirrors to remind me to take the disc locks off. The tag is high viz, no scratch, and fits easily in a pants or jacket pocket. I had considered disc locks with built in alarm, but found them to be bulky, and read numerous reviews about what a pain resulting false alarms were. Sometimes using the "KISS" ( keep it simple stupid ) rule is the best way to go, and at least for me it was.
