I'd just like to add on thing. If you for some reason end up wanting and getting a road bike the fit will be a little different once you start loosing large amounts of weight. If that is a goal. Note this also depends on where you keep most of your excess size. In my case I have problems in the mid section, still do (I swear that is where those last pesky 20lbs are). When I first got my bike the fit was fine but now that I can get lower and more streched out because all that fat isn't in the way, now it sometimes feel like the reach is to short. I also had to raise the seat quite a bit as I lost weight.
