The point I'm trying to make, although I'm not very
articulate in saying it, is that, because the telescopic
pole is fixed rigidly to the hub, and hinged at the rim, if
the pole were horizontal to the ground, then (hopefully) the
pole would not be able to bend upwards at the hub, and it
would not be able to extend or compress, because the force
would be on a different plane, and so the wheel would be
forced to hinge around the end of the pole.
If you're hopping with the pole horizontal, then your
weight, acting downwards on the hub, is effectively
rotational force on the pole, and we know from bitter
experience that the forces involved in trials, muni, and
hopping, are enough to bend and break even the best
equipment.
One of your screenshots seems to illustrate the situation
I'm trying to describe, In the pictue it shows the pole
bending downwards but it doesn't take into account the fact
that, when you're hopping, you're standing on the pedals,
and keeping them horizontal.
Basically, it's a very good idea, and I'm sure it could
work, but your drawings don't seem to take into account any
of the torque that would be transmitted through the metal
pole, and because in the drawings the hub can rotate freely,
the pole behaves as it would if it hinged at both ends.
Would it be possible in the software you're using to make it
so that the hub can't rotate?
How easy would it be to model the wheel actually in use? i.e
torque on the hub, weight visibly acting downwards, ground
visibly acting upwards.
It is of course perfectly possible that you've address all
these issues, and I just can't see it, in which case I
apologise for wasting your time.
personally I think you desgin a fully enclosed unicycle,
because I have to ride down to the supermarket now and its
just started pouring with rain.
