I've resorted to the multiple bike technique - basically I never leave a nice bike locked up and unattended if I can possibly help it. I've got an old Claud Butler set up as a single speed beer bike for when I go out and have to leave the bike locked in some shady urban spot. It looks like shite with a certain amount of real (non-structural) rust on show and plenty of dirt. But I actually love riding it - the relaxed frame geometry and big tatty saddle give a ride as soft, silent and comfortable as a well-worn pair of slippers.
