Overall in riding comfort, it is "between" uprights and recumbents. The
seat is a lot better than a bicycle saddle (I ride it without padded
shorts) but is not as good as a recumbent seat and only allows one
riding position, which can get on you after an hour or so. The seating
can be very upright, depending on how you position the handlebars. There
is no hand pressure or neck strain to speak of.

The seating would be my concern as well

Since you are so upright..... wont your but really
start hurting after awhile or so?
