"How is it up hills?" I have not done any steep hills, but I was able to do smaller hills.
"Is there an option where you can pedal or row?" There are no pedals, it has fixed foot rests.
One problem I had was that my left arm is weaker than my right. This caused steering problems after about 1.5 miles.
"Not much ground clearance under that swinging beam, though." I was very carefull going over curbs, pot holes.
