“Japanese Student Takes Flight of Fancy, Creates Flying Bicycle” [https://www.youtube.com/watch?v=ZJrJE0r4NkU](https://www.youtube.com/watch?v=ZJrJE0r4NkU)
*Edit: Far beyond regulations and air traffic control issues, only regarding to physics:*
I’ve just seen this video of a Japanese student that has achieved making a flight of about 200 or 300m with a mechanism that turns the pedalling we normally do in a bicycle to the turning of a propeller.
Now, if we as humans and a very great bike can reach 40-50 mph (and very light planes such as cessna can take of with only 60mph – not to mention Bush Planes – all of these weighting easely 4 to 5 times the weight of a person + an extra light airplane design, specifically created for that porpouse) – why does this seems too hard to achieve/sustain? I can only guess its a matter of efficiency (or the lack of it), but which one of them?

I see two big issues with your question. For one, you are vastly overestimating the speed a person can ride a bicycle. For example, the most famous tour rider who tested positive for PED’s and rode on bicycles that cost more than most cars only averaged 26mph. But the biggest issue is, you watched a video of someone doing a thing, and then asked why can’t people do this thing? Is your question, why don’t more people do this? If that’s the case then it’s obvious from the video, it’s not practical.
