Possibly riding the OneWheel in the bike lane violated the contest's rule about not violating any traffic laws? (I don't know where they are or aren't considered street-legal in Seattle.) Edit: I did a brief web search, and it seems like these devices are probably allowed to be ridden in bike lanes there after all, but I didn't find anything very authoritative.
