Well a "semi-recumbent" fits about halfway between an upright
and a full recumbent. Recumbent bikes have a chair like seat and
many models have handlebars next to the seat as well as in front of
the seat, and also provide better back support, the Semi-Recumbent
exercise bikes are the same design as recumbent except the seat
position is higher you are in a more upright (less recumbent)
position,
