I had a Puch Maxi/Newport originally I rode for years that was fairly comfortable with a long seat that was slammed on the rack. After I rode a Tomos Streetmate for awhile, that was very cushy and with slightly taller bars and regular pedals it would have been an excellent cruiser but I went with low bars and short pedals to go "fast" and clear a big pipe lol. I also rode a Honda Spree to work just fine for a few years. Just recently I bought a super short cafe franken bike, it is by the most uncomfortable moped to pedal start I've owned but once you get riding it's fine so I guess we'll see how that goes. Like I mentioned early being a little tucked only becomes a problem over long distances, but if you just stop and take a break every now and then to stretch your bones anything should be fine.
