Hey! There is a a plethora of information on bentrideronline.com about recumbents.
There is a wide variety of recumbents available. They are a blast to ride.
I have two that have two wheels and another on order.
My trike is a hoot. It is a Challenge Concept with USS. I ride it on the bike paths during the week. Like snowshoeing, trikes are a lot more fun than one would think.
You might prefer Under Seat Steering USS if it works better with your elbows. ASS (Above Seat Steering) has a funnier acronym.
Got my third Synvisc shot recently and hope I am ready to go. Can not ride like I used to, but it beats daytime TV.
