Re the slipping of wheels, I discussed this some time ago with someone
from Semcycle (for a two-wheeler). Actually, there was an additional
issue of lateral movement to the extent that the tires would run off
each other. He recommended in general that the bottom tyre be pumped
quite hard (as it takes your weight), and the top tyre not harder than
needed to prevent slip. That way, the top tyre would fold slightly
around the bottom tyre, and also the top tyre would be more flexible
to absorb and "correct" some lateral slip without accumulating in too
much sideways movement and consequent run-off.
I would think that the frame is designed to take vertical stresses
Jorga has the two-wheeler almost down. I have only one word of advice:
"practice". Jorga rode along a wall rack for hours, then holding two
persons, then one, now a half (i.e. one but very loosely).
