The quietest Orange County Chopper yet: the electric Siemens Smart Chopper

The beefy gents at Orange County Choppers have surprised us a few times before, going out of their normal raked-out design brief to customise a Ducati Monster 1100, for example - but they really turned heads this week when Paul Teutul, Snr, presented the company's - and perhaps the world's - first all-electric chopper. Commissioned by Siemens and built using recycled steel, LED lighting and environmentally-friendly water-based paints, the Siemens Smart Chopper features a 27hp brushless motor good for a top speed in excess of 100mph, and enough battery life for a 60-mile range. And it's going up for auction.
