The World Championship of Custom Bike Building is a competition held annually by American Motorcycle Dealer (AMD) magazine. The first competition was held in 2004 as an extension of the AMD ProShow custom engineering competition held in Europe in conjunction with Custom Chrome since 2002, which by some was already unofficially acknowledged as a European championship[1] The top three finishers from the European Championship are rewarded with an entry to the World Championship and an expenses contribution to help with bike freight costs. There are also a number of affiliate events in various countries in Western Europe as well as in Russia, Japan, Australia and Mexico.[2] The winner of each Affiliate event also wins expenses towards competing at the World Championship each year. The judging of the World Championship is done by 'peer review', in that all competitors collectively decide the winner, together with a select panel of invited judges from the press and aftermarket industry.[3]
