I say cruiser, if you can add foot retention.
It has never made sense to me for people to ride the lightest, most efficient bikes for 'exercise'. Seems to me you should ride the heaviest, least efficient bike to make the most out of your workout time. I mean, people who lift weights don't do it with tiny little carbon fiber bar-bells, right?
The foot retention caveat is because you work more of your leg muscles when you can pull up as well as push down.
