Tour de France monocycle

I’m not sure how many of you have been following Tour de France (it’s a bit far
to unicycle I know) but in the closing credits of the highlights show on SBS in
Australia, they had a guy in a monocycle. The only shot of him showed him going
head over heels in it. The cycle wasn’t motorised like the one on the unicycle
page, but was of similar dimensions. Did anybody else see this / know who it was
/ where i can get one??
