"Nuclear Cowboyz." It is hard to understand what about them is "nuclear" - by all indications, their bikes seem to be gas powered. And because they are riding motorbikes, it's hard to consider them "cowboyz" of any stripe. Cowboys are usually on horses.
Also, watching that video, I wonder how different synchronized motorcycles is from synchronized swimming, diving, dancing? Very different, apparently, because synchronized motorcycles is basically the climactic battle in a weapon-less science fiction war in a apocalyptic wasteland. In that way, it is actually more like "you got served" dancing.
All my troubles on a burning pile.
