First, let me freely admit that I know nothing about this unicycle
except what I have seen and read from these postings. However this is
the web, so I won't let that deter me....

I am *guessing* that when the tab is disconnected entirely and you
pedal, the hub whirls around in the opposite direction and the unicycle
doesn't go anywhere. So this is actually a three speed uni: fast, slow,
neutral! Harper let me know if I am way off on this.

I have been mulling over this shift on the fly problem, with gears and
chains you always have one of two problems:

1. freewheeling, unable to provide torque while the chain is moving
(typical bike scenario)

2. locked, both sets of gears are momentarily connected and the shaft
won't turn.

It seems like of these, number 2 would be more tolerable: that you would
stop at the top of a hill, shift, then head back down. A very
interesting problem.
