It would be remiss of those on this forum not to suggest 2, one for you, one for your wife.
I'm 6'2'' and have a standard (580mm) seatpost. I do however pull the seatpost up to the full height so a lot depends on your inside leg and how much you will use the B. My personal preference is flat bar, but try and see which you prefer.
It'll be predominantly her bike for train commuting 3 days. I'll be using it sporadically. So sounds like a flat bar and normal post to start and we can go from there. I'm assuming swapping bars isn't too traumatic an affair?
