This shows how the fiberglass box/fairing is mounted. I used 1"x4" polyethylene barstock to make the mounting bracket.
This was also posted under "recumbent".

Very shiny because I sprinkled aluminum powder between coats of paint.

This is a photo I took a few months back.

This bike was developed at the same time as the other one, but I molded the fiberglass directly to the frame, so it cannot be unbolted. This is the bike appearing in my avatar. Both these bike fairings are based on diesel truck spoilers.
