Home-made unis

Has anyone made a uni out of an old bicycle by sawing off the rest of the frame
off the seat-column post? Jamming the freewheel and fixing the bike in a
particular gear should yield a uni with pedals out in front of the rider?

I have seen a drawing of such a contraption in “Creative Clowning”, but I wonder
has anyone here made on it?

One side effect of this is you’ll get a wheel/forks/handlebars thingy “for
free”. (What are these things called?)
