ProForm XP XP 400R Recumbent Exercise Bike —
My wife and I were able to assemble the bike very easily using my own hand tools. We did'nt try the tools that came with the bike. We were both impressed with the smoothness and how quiet it is. We both use it two times a day and have had no problems in the approximately one month we've owned it. The seat adjusts very easily. I'm 6'1' and my wife 5'3". We are both able to ride comfortably. We both appreciate the seat adjust lever as opposed to the screw adjust knobs used on some of the other type.
