Here is how I carry my u-lock. I just spin it around and lock the bike to a rack by using the handle of the bike. This is just for a very short time while in a store or coffee shop, I would use this plus cables, chains, large vicious thugs or dogs for anything longer. If you carry a strap for holding the bike together when folded you could also use the strap to tie down the lock so it has no chance of bouncing but I use mine on trails all the time and don't notice any problems.
