Definition too specific
"A racing sport in which individuals or teams compete at riding bicycles."
It's not, though. That's a bit like saying all horses are race horses. The vast majority of cyclists don't race. 'Cycling' and 'cyclist' are actually defined legally too, since cyclists are road users like motorists, motorcyclists, pedestrians etc. Someone who knows and cares about this more than I should probably split the article off into an article on cycle racing and have the main article on cycling balanced between cycling as a transportation method, as a leisure past-time and as a racing sport. –Tom Morris 20:20, 14 November 2009 (UTC)
