What Happens If You Put A Giant Propeller On A Bike?

I dive into my old collection of Popular Mechanics magazines and get inspired to build something! I found Ernest Winter’s air screw bicycle, so I tried to build it. He claims it is able to hit 20 miles per hour, will I be able to match his speed? How will I build the propeller? How can I power it with my feet? Will it go fast enough to fly? How does it compare to a giant fan? I go on the journey to test it and more!
