A guy who calls himself 'Rocketman' has built a jet-propelled Harley-Davidson that can travel from 0-60mph in five seconds. Packing two jet engines and capable of hitting speeds of over 200mph, the Harley is based on the classic 1926 flat-track racer.Super-mechanic Robert Maddox customised the two-wheeler for a bike racer in Illinois.

He says its handling is 'smooth and stable', although it is so powerful that it 'wants to pull your arms off'. The Harley Davidson SportJet is now for sale at auction on eBay for $20,000.
