I finally got motivated enough to start building the recumbent that I've talked about making for years. I'm following an EZ-clone design from here
http://www.recycledrecumbent.com/. The bike started life as a black colored tall frame schwinn road bike and a white colored Belgium made Trak (not Trek) road bike that used knit style tires. I've pretty much finished fabbing the frame at this point. The bare frame weighs in at around 8lbs 8 oz. The schwinn was a pretty heavy frame. I still have a long ways to go before I can test ride it. The seat will be my biggest challenge. Here are some pics of the frame as I was finishing the rear triangle alignment and then adding the 2 bottom rails. All that's left for major frame work is to finish closing the joints for the bottom rails to rear triangle and bottom rails to crank mounts then weld em up.
Edit: I'm not a bike expert and I don't know all the proper nomenclature for bikes and thier parts so bear with me.
