If you are handy with tools, need a cheap comfortable bike ride, this may help. A no-weld recumbent built from two old ten speeds. Hack saw, drill, chain tool, carriage bolts, duct tape, plywood, foam, vinyl cover, junk 20" BMX front wheel, some junk derailleurs, hose clamps, a set of longer cables and a steering head extension. Oh, and a piece of wood behind the steering head. The design is from this site:

I have been riding this recumbent for over two years. It's ugly enough to park unlocked, a bit quick on the steering because you lose some trail with the 20" wheel. I have baskets on the back now to haul groceries with. I paid $30 dollars for the womans MXT frame style ten speed (the seat post on this SKF MXT frame down tube is lower so you can lean the seat back to 45 degrees). A junker man's ten speed provided the front "boom" from it's down tube and gear set. The forks from the man's ten speed straddle the woman's steering head.(Am I allowed to say that?) and the front boom slips over the tube from the forks. Anyway it took me about a week on and off to make. Total investment $90.
