Like many posters have said, you more than likely didn’t pick the wrong bike you just need t adjust it for the ride you like. It takes time to get used to a new bike. I started out with my Revive because I knew from the first that I wasn’t in the physical shape I needed to be to get as road bike and enjoy it from the beginning. The comfort bike was easier on my back and gives me no problems with my hands or arms. I started putting on some miles and discovered that if I started pushing it to keep up with faster riders I developed some soreness in my lower leg. After a while the soreness decreased and I could pretty much ride the Revive up to 40 miles with little of no discomfort.

Next I decided I wanted to try some dirt and some climbing so I bought a MTB. My first two rides were 25 and 22 miles within a week. My back didn’t bother me but my arms and hands were very painful. I liked everything else about the bike so I went to my LBS and got a different headset that brought the bars in and up till I was comfortable with it. Now the MTB is a dream to ride. Not as easy on my body as the Comfort bike but faster and much better suited to the dirt. I still need to do some tweaking but my LBS suggested that I ride it till I need to replace something so I will have a better idea what I want.

Most of my riding friends have road bikes so I decided I needed a road bike for longer rides. I will admit that I only have 50 miles in two rides on the road bike but I was surprised that the seat didn’t bother me more. Now the soreness is in my upper leg and lower back. Not as bad as it was during the first 500 miles on the Revive but soreness nonetheless. So I have learned to get the bars in the right position and the seat adjusted for a diamond frame but I will have to get used to the riding position of the road bike just like I had to on the MTB. My problem now is personal fitness not getting the bike fit to me, and if my back starts hurting I can always ride my Revive for a day or two.
