Nope. Those things had two smaller wheels that ride inside
each tire. The main tires have no inner sidewalls, and the actual
suspension is a bar that reaches into the inside of the main and has
two small wheels on each end of it that ride on the inside of the
mains' treads. They have a wheelbase of 10" or so, enough to keep the
machine upright. Fools lots of people. The flattish-looking main tires
give the game away to anyone with any mechanical knowhow.
A guy here in our area built one and drives it in the local
parades. Has hydrostatic drive, too. Runs the smaller wheels.

Wow! never expected to hear from anone who knew of one! That sounds pretty
complicated. There can't have been many guys who built those. So the outer
tire just flexes and acts as a sort of track for the inners and, i suppose,
they just use differential power and/or braking to steer.
Cool!
I must have a look for the old plans..

So, someone did do at least one copy of it. Might write to Mr Schlatter
and see if he has any plans copies.. Not that I need another project!

Looks like probably only one was made.

That's pretty cool. I always thought those one wheel motorcyles you drive
from inside the wheel would be a blast to try too.
