Add me to the list of can't stand and pedal at the same time yet. Well I haven't tried it on the mountain bike yet, but just flat out can't do it on the road bike. (Thinking it might be easier to learn on the mountain bike). I also am not a spinner. I have a pretty slow cadence. Unfortunately due to moving it's going to be another probably two weeks before I can get back on my bike again. One of the last times before we started moving that my husband and I went out on our bikes he wanted me to try an easier gear and a higher cadence, and my legs felt like jello within a minute or so of trying that. He rides at a good bit higher cadence than I do and doesn't understand why I ride at a much slower cadence.
