Saw your post at Recumbents.com. Did any of the projects match your concepts?

Thanks for the interest
derailleur hub? blown nose cone? tail fairings?
I have no idea what I'm doing

1) Derailleur hub is the one with the gears on the outside. Road bikes and mountain bikes use them.
2) Blown nose cone is a bowl shaped piece of plastic formed by heating sheet material and using air pressure or vacuum to force it against a mold.
3) Tail fairings are the body work behind the rider.

Try the BMX to recumbent conversion file.

The Trailmate Fun Cycle 20" is a single speed delta trike, is that what you had in mind?

kinda but that is not a trike

See The Work Shop and velomobile.net for building information.
If all that is too intimidating check out the Bicycleman.com in Alfred, NY. I have known Pete Stull for many years

Sorry I haven't updated in a while. Nothing has really happened; I was working on the frame blueprint but ran into an issue between the handlebar pivot (shortened head tube) and the seat bracket. They want to be in the same place. I'm going to have to notch the seat bracket, I think. I got pretty distracted by mountain bikes' charms, but still would like to finish this project.

20GT:
If I were smart, I'd build one of these instead: The Recumbent Bicycle and Human Powered Vehicle Information Center

I'll post the other blueprint(s) when I finish them, but I am also really short, so unless you're 5'2" you would have to do some modifications to make it work.

I decided enough is enough, and finished the frame blueprint. I omitted the disc brake mount, the holes in the seat mounting plate and any cable stops, etc, but overall, this should be pretty complete.

Also including the fork geometry from last year for reference:

Next step, I guess, is to buy the steel for it. Not going to happen immediately, but at least I'm ready.
