Walmart now sells a rear suspension recumbent bike for less than $300! It is called the Hyper Insight.

I suppose you could easily add a front suspension fork to this bike and have full suspension for less than $450?
Hey AB,
Linking to your WalMart buy, here's the pic.
I read the 3 product reviews from customers, and the bike look likes a spur of the moment bargain, where the engineering isn't "great", but acceptable for limited expectations.
In other words, it's generic, and the customers mentioned things like "assembly required" and "parts missing", a deadly combo for some folks.
This bike wouldn't work for a GEBE setup, because of the 20" wheels. Plus, I was told to look for a steel or alloy frame, and the WMart description says this bike is aluminum.

However, the next step up the pricing ladder, at $800 seems to be THIS, imho:

Since I'm in photoshop, I uploaded thatDay 6 Dream 21, that the boys from Oxford bought, it has a 26" wheel on the back. (For a GEBE kit, this requires side straps instead of the front strap.)
The seat on this bike is superior to mine on the SunEZ Sport. You can't tell from the picture, but dangling off the back of the seat is a multi-pouched carrybag. Very handy.
