Coming back to this page in 2021, it's hard to believe that I have
been working on this project for over 10 years. Somehow, this
little bicycle has survived being sold in all that time, though
I've tried!

The project as a whole was stalled out by many things over time,
including lack of funds, but mostly lack of parts. The front fork
is very weak and the bottom bracket has a custom thread pitch, so
the normal options weren't really in the cards.

I stumbled upon a recumbent fork that would work after being cut
down, and purchased it along with the motor. I pressed a new
headset into the frame after a lot of research, and the bike is
currently at the shop getting tuned up and being converted to a
"fixie" due to rear hub issues.

The fork, if anyone is curious, is a Sunlite Threaded Recumbent
Fork in the following size:

"20" / 250 x 155 x 22.2 x 27.0mm"

The head tube had to be shortened, but that's quick work for a
bike shop.
