Many thanks in advance.
You found correct... the Birdy is definitely also a medium ie 55cm top tube bike. You would need the sports stempost and you could quite easily fit a stem to the stempost, putting the bars further forward again. This would increase the tiller effect but I don't see how that is bad,
per se. The sports stempost puts it out of knee's way. I'm 5'10 and my body and arms are at 45deg to the horizontal.
