I use a D-lock and a chain of some kind: most bike thieves only carry the tools for one of these. Put it in a public place & don't have any 'quick-release' things on there - I got my sadle nicked on my 1st day as courrier
If it gets nicked go to Bricklane market on a Sunday morning: chances are it will be there
But most importantly, don't loose your keys: we had to hacksaw through a lock on Trafalgar square: the police just ignored us & most people laughed at us
(didn't help that we were there for the 'Cannabis EducationMarch'
