I suppose you'd cut the cable that is holding the bike to a fixed object , then toss the bike in the van and drive off . Deal with the ring lock at your leisure. In my garage, I think it would take me 5 minutes to get that off. Dremel to cut the straps holding the lock to the seatstays, screwdriver to detach the lock from the seatstay bridge, undo quick release, rotate the wheel to move the lock a couple inches away from the seatstay, bolt cutter to the ring, done.
