What is the difference between recumbent bike &stationary bike?

I had to look it up, but the Edge 280 is a recumbent exercise bike sold at Wal Mart among other places. When your referring to a stationary bike, I believe your talking an exercise bike with bike handle-bars, and a normal looking bike seat. The big difference is you take weight off your hands and butt while exercising with the recumbent, on the stationary you usually don't.....

As Scott said in your previous reply, a "recumbent" is a bike you ride on the road, but it's not your ordinary bicycle. A recumbent is designed in such a way that you're virtually lying on your back and you're just a couple of inches off the ground. (They're much faster than ordinary bikes, because of the wind resistance factor.) A "stationary" bike, on the other hand, is just a bike that doesn't move (that's what "stationary" means, remember?). It's used for training, rather than going out on the ride. It can be your ordinary bike held upright by some kind of device, or ridden on rollers, or it can be a bike-like device used in gyms, etc. that you ride for training.
