Here's my Xtracycle....
That snowfall was interesting, since it alerted me to the fact that my wheels leave tracks over an inch apart when I'm riding in a straight line! I suspect I didn't dish the rear wheel correctly.
I don't know what the frame is; it's aluminum and I found it in a dumpster with little or no paint on it; I painted it with a white primer and then wrapped the whole thing with white reflective tape for a remarkably good looking, and rather tough, opalescent finish. And the reflective effect is striking.
