I figured that out too, for a coin, or a wheel only. You argued that
the polar momentum of the unicycle and rider is quite small; yet it's
of course not negligible. And then a rider can increase it by
stretching out his arms right? And even further if he would hold
weights. Would he then need to lean more to make the same turn
especially if the wheel is light?

It still is a bit elusive to me, but maybe we should stop the
discussion here, I think we've drifted off-topic for too long.
