Don't get the wrong impression you can build a "weak" frame because the
wheels support each other. The wheels *do not* support each other. You
jam them together as tight as you can for traction, but they don't hold
any weight. Your frame still has to do that job.
Also depending on your wheel size, a 3-wheeler will be taller than a
6-footer. Do the math. Remember your pedals will be on the top wheel,
and you'll be however high above that you would be on any other
unicycle.
3-wheelers are very visual, especially if you put something in the
wheels so people can see them rotating in opposite directions. They're
great in parades, and unlike a regular giraffe they're much better for
wheel-walking. But they are also heavy, and can be damaged if allowed to
drop. Another reason why I guess it needs to be at least as strong as a
giraffe frame...
