The older I get, the harder it is to swing the leg over the saddle! I have two bikes, an old Raleigh road bike and a converted MTB I use for touring and commuting. The MTB has a small frame and sloping top tube. If it wasn't for the sloping top tube that I can step through, I probably wouldn't ride it as much. I have a hard time getting on/off the Raleigh so it just sits.
My next bike build will definitely have a deep sloping top tube or be a Mixe. Function over fashion. It's always been that way for me.
