I rode my wife's MTB since my Peugeot is out of commission. I had to raise the seat, but it's a guy's bike so it fits me okay. The seat is angled for a chick_oops_woman so it wasn't entirely comfortable after a while.
Oddly enough I was cruising at about the same speed. What does that mean? I guess the Peugeot had oodles of drag from the worn out drivetrain or something. Gonna go check out new bikes later. I feel like I'm buying a new car or something.
