Thanks all for the various definitions, but I still have some quibbles and
questions.

You can probably safely change British to Commonwealth. The general public
here in Australia seem to make no distinction between unicycle and monocycle.
(The reason I brought the topic up was that I felt silly correcting them, when I
wasn’t sure of the difference anyway.)
FWIW, the Shorter Oxford English Dictionary does not contain “unicycle”. It
defines “monocycle” (this is from memory) as a “one-wheeled velocipede”.
I tried to work out which was more appropriate by working out the etymology, but
it seems that while “uni” and “mono” come from the Latin and Greek respectively
(or was it the other way around? - I should have written it down, or brought my
Shorter Oxford to work!), the word “cycle” is derived from both Greek AND Latin.

After some thought, I decided that my answer to that is “yes.” If someone can
pass some of the Unicycling Skill Levels while only using one wheel on their
bike, why not declare it an honorary unicycle? If I ride a standard unicycle
while holding an unattached wheel in my hand, it is still unicycling, so what’s
the difference. This way, “multi-wheeled velocipedes” where the wheels are
stacked on top of each other (only one touching the ground) can be
“multi-wheeled unicycles” despite the oxymoron.

Sounds good to me. As long as it is clear that this definition excludes
wheelbarrows… and Ansett air-craft when some of the landing gear fails.
