Agree that we need to know what bike you currently have.

What do you like about it? What do you not like about it? Has your fitness improve that you're ready for a little less relaxed position? On your current bike, is something uncomfortable when you get to 20-30 miles? If so, what part of your body is uncomfortable. And is it just uncomfortable, or is it hurting/painful?

There's nothing wrong with the bikes you listed, and some people do ride those bikes for 50 or more miles. But as Bassjones said, most people will find them uncomfortable for riding rides that long.

But it would be helpful to know where you're starting from.
