Alex Calothis built this recumbent from a couple of old bikes salvaged from the tip and some mild steel tubing. The rear fork is from a Saracen AWOL with an elastomer damper.
The seat is laminated out of two sheets of 4mm ply glued up on a frame, and is suprisingly comfortable - much better than an upright bike!
The front wheel drive system works well and uses a couple of idler pulleys from McMaster-Carr. The turning angle is limited but this is only a problem at very low speeds. With the small front wheel the bike is a little too low geared and could have therefore done with a bigger chain ring.
The whole thing was welded using a small arc welder. For more on this bike check Alex's web site.
