Sam sez, "The Confederate motor company make motorcycles that rub together heritage and futurism to produce quite astonishing looking machines – the kind of bikes that look like they're going fast when they're stood still. They also have an attractive air of menace in their styling combined with a sort of 'Mad Max' craziness. The kind of bike one of Stross' characters might ride."
I can see one of Charlie's characters riding this thing, but only if he gets to make fun of the overblown marketing copy on the site.
(Thanks, Sam!)
