To be honest, if you want a SuMo, then get a SuMo; You don’t need to find a way to justifiy yourself of getting one. All the lack of aero and gearing preventing you from speeding, IMO, is just nonsense.
Get a bike you like and you can afford, respect your body by wearing gear, don’t go too crazy on public roads and have fun. Unless you know how to fly, riding will be the closest thing next to it. Enjoy! :thumbup
