Jen, I feel a lot like you. The set up of the bikes makes you feel very "upright" and not at all like a real bike set up (road or mountain). I do like the belt driven drive, although on this bike it takes way too many turns to adjust your setting. Phew! I'm just trying to get comfortable on the bikes. It's kind of hard to instruct when you're not at ease on the bike you're teaching from.
P.S. I am very aware that many of the participants don't ride outside...but, I also have many that do and replicating a ride is hard when the bike doesn't give them that ability.
Vertically challenged, but expanding my horizons.
