Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Flying bicycle.

Flying bicycle.

Call me crazy if you want but the other night I went to sleep after reading about the Akashic Record, which suggests that all knowledge already exists in the universe if you can tune your mind to access it. I dreamed about a flying bicycle powered by only the wind and the rider. The rider wears a hard backpack device on his back which folds out to a device that resembles a hang gliding kite. There are four peddle-powered fans on the sides of the bike that provide forward movement and control. The bike is steered just like a ground bike by shifting your weight. Take off is facilitated by getting up speed to about forty mph. so downhill takeoffs are probably the way to go. Ok you can call me crazy now.

I assume you've read about the English Channel Crossing back in 1979.
It wasn't a little thing that could be stuffed in a backpack. But, a lot of things have changed in the last 40 years too.

I don't believe you can use wind power to generate lift, as once one is airborne, the lift is the difference in speed of the plane and the speed of the air. Wind, of course, will affect one's speed and direction.

Solar power is also a potential power source, but the Solar Impluse, for example, weighed nearly two tons, and the Impulse 2 over two tons.

Did the Gossamer-Albatross have two wheels?

This was pretty light:

Still, it would be fun to make a solar/pedal hybrid.

Perhaps it could be made lighter with modern composites, or more powerful with modern solar cells. Still, 205 lbs isn't bad for a plane with a 47 foot wingspan. Many velomobiles are a good fraction of that weight.

Not possible at the moment, at any price.
The whole idea is flawed.

Human powered flight?

There's a club for that. They hold an annual contest as well.

BHPFC Home

The aircraft take the shape of very long winged gliders with a bicycle powered propeller.

Some students in engineering did a plane powered by a rider (a friend of mine).
