Please explain how the Top Tube effects a fit. I don't want a bike with the Top Tube. I prefer the walk through as that's what I'm used to and, I have been told I also have a short torso and long legs.. I don't dismount probably effectively and that top tube hits my tulips and that's not good. So I prefer no tube in the middle.

Glad to read your excitement about a new bike. I'm a beginner but I'm here to learn.
