Bikes that are fitted with aircraft engines? Take this then, the latest from custom bike builder Jesse James. Sure, it looks outrageous, but there’s more to this bike than just the styling. It’s powered by an Australian-built, seven-cylinder, 2800cc, radial aircraft engine, which makes around 110 horsepower. We don’t suppose it would be as fast as the jet-engined MTT Y2K, but still, the Aero Bike shouldn’t be too bad for pottering around town. More on this machine on the Cycle World website.
