My grandson just had to have this fiberglas seat that I got from S&B Recumbents ... the bottom mount was sawed out of a Direct TV mounting bracket ... I kept a bit of the bend in the rear for rigidity. Welded to the frame ... there is no flex in it ... and it's wide enough to give good support to the seat bottom.
About halfway up the seat back ... look inside the purple rim ... and you'll see the bracket that came with the seat. I just welded it to the frame. The seat is a compromise angle that will meet the needs of the grandkids. Next to work on the steering.
I'm making the Above Seat Steering (ASS or OSS) mechanism. This thing has 2 headsets ... one above the front fork ... the other in front of the seat. They currently are linked by a rod (which I borrowed off my lowracer). When the rear one is turned ... the front one turns simultaneously in the same direction. Monday I'll work on the short riser that connects with the handlebars. I'm also working on a different bottom bracket unit. You have to cut up multiple bicycles to get the parts you need to make one of these ...
