Dang, people, can't a kid build a custom unicycle with his dad? I didn't
see anywhere that he expects it to replace sliced bread as the
next-best-thing; sheesh, he's just a kid! I did the same thing when I
was 18, and I'm glad I didn't have this group to discourage me before
I'd even started.
If it works, great. If it doesn't work, maybe he needs to try again. In
either case he learns something. If he wants to share his design,
people who know what they're talking about can offer helpful
suggestions.
For Borgschulze, I have ridden something a little bit like your
drawing. It was simpler, with a simple pair of gears to transfer power
from the cranks into the axle, making for a "standard" two-wheeler
(reverse drive). Though it worked, you could feel a percentage of the
input energy being sucked up by the gears. I think on a design like
yours you'd have to allow for an even larger percentage of energy loss
through the drive system. But, that's one of those things you never
know until you build it. And even then you don't know because maybe you
can improve what you built. So don't discourage people from trying. 🙂
