I think the definition Jack that gave for ONE-WHEELED VEHICLE would be
closer to my preference for UNICYCLE. I dislike the notion of calling
obviously multi-wheeled vehicles "one-wheeled" merely because only one
wheel is in contact with the ground.
What about bicycles when they are ridden in a "wheelie", ie, with only
one wheel touhing the ground? Are they one-wheeled vehicles, or
unicycles, for the duration of the wheelie?
Another problem with Jack's definition is that it doesn't specify that
the single wheel is to be the *sole* contact with the ground. Consider a
hypothetical "ordinary bicycle", such as a Pennyfarthing, with the minor
wheel replaced by a skid. Should this be considered a unicycle, when the
skid is providing substantial support? (Hmmm, maybe it should...)
On the other hand, consider a standard unicycle being ridden as an
ultimate wheel, with the seat dragging on the ground behind the
rider. Is it no longer a unicycle because the seat is in contact with
the ground? Perhaps we need to discriminate on whether any contact
points, other than the specified one wheel, provide substantial
support to the rider(s).
So:
UNICYCLE Any kind of vehicle which, when in use, uses a single wheel as its sole
supporting contact with the ground.
Note that I chose "when in use" instead of, say, "normal operation". I
want to allow bicycles to be considered unicycles, for purposes such as
eligibility for competition, so long as only one wheel touches the
ground (thus, providing support) throughout the duration of the
competitive heat or performance.
>BTW, many European languages use some word similar to “monocycle”.
At the Unicon in Quebec City, our hosts used "monocycle" (except maybe I
don't have the French orthography correct) for what I would call a
"unicycle". This grated upon me intensely, as I had been raised in the
American unicycle vs. monocycle distinction as outlined by portions of
Jack's message (that I did't include above).
