No, the bike is going another way. Bicycle makers craved the airy lightness of being. They were about to give us the airplane. So we turn to the part on flight. Now fancy mixes with fact.
Bicycle pedals drive propellers to steer balloons.
Here's a weird man-powered helicopter with seven propellers. It never could've flown. But there's Otto Lillienthal's glider. It flew very well indeed. We move on to ships.
