Many motorcycles can travel up to 165 mph in sixth gear. The average Cessna private airplane, which has a single-engine takes off at about 40 miles per hour. So why can't a motorcycle fly? Only one reason; it does not have wings and it does not have a propeller.
However both of these problems are easily solved. The rear wheel of a motorcycle could easily be retrofitted with a propeller adapter and NASA has already designed unmanned aerial vehicles with foldout wings, which blow up. Many home built aircraft are open cockpit and many ultra-lights have no cockpit in all. You sit in a seat and basically buckle in and go for it.
How would a motorcycle rear wheel propeller adapter work? Well, consider if you will the little lights that that are used on bicycles, which would run on the tire as it went around and make electricity. Similar to this but, a small rubber wheel attachment on a lever could be pushed onto the back motorcycle wheel.
The smaller wheel would have a short chain on it and spin a propeller. When you give it throttle, the propeller would go round faster and the wheel would move even if it were not touching the ground. Building a motorcycle rear wheel propeller adapter is a key component to getting your motorcycle to fly. Please consider this in 2006.
