In reply to tintinandpip:
I'm surprised more people don't. My old moped was cheap to run, cheap to insure (<£100 per year) and great for getting out and about.
I didn't climb at the time but Kalymnos is showing me it's easy to get out and about with one.
I guess one problem is that the CBT test limits you to a single person on the bike, and the full text is pretty expensive. I think one for a uni student could be great though!
