The Wright Brothers: Bicycle Geniuses


Part 2: Focus on the Air

Into this 1890s bicycle craze stepped Orville and Wilbur Wright. They opened their own bicycle shop in Dayton, Ohio, in 1892. Wilbur had bought his first bicycle in the 1880s. It was a highwheeler. Both he and Orville were fascinated in how it worked and were determined to help make it better. They both bought safety bicycles, and Orville even began to enter bicycle races. The family business came first, however.

They sold and repaired bicycles, and their shop made a good bit of money. A great many people wanted bicycles in those days because the automobile hadn't been invented yet and the train was too expensive for many people. But the Wrights wanted to make their own bicycles. They worked on their own designs, in the back of their shop, for a few years before reaching success.

In 1895, they introduced the Van Cleve. (It was named for an early settler of Dayton.) The following year came the St. Clair. Both models sold very well. But the Wrights weren't done tinkering.

To each bike they sold, they added a "self-oiling hub," so the gears wouldn't need to be oiled every few miles, as was the case with other bicycles of the day. In 1900, they added pedals that don't come unscrewed. (Bicycles today still use this idea.)

The success of the bicycle shop allowed Orville and Wilbur to buy lots of materials to use in their experiments with flight. They were still fascinated by things that flew, like kites and birds, and they now turned their attention to making a machine that people could fly.

It was here that the bicycle came in handy again. One day, Wilbur squeezed an empty bicycle tube box flat. He noticed how it looked when he twisted in his hands. (The flattened box is the exact shape of the two-winged glider that the Wrights would produce just a couple years later.)

You can also see the bicycle chain that the Wrights used as a propeller on their plane. (It should be pointed out here that the Wrights had to invent the propeller as a means of propulsion.) The double-triangle design of the plane also looks a lot like a bicycle.

And one day in 1902, Orville and Wilbur took turns pedaling one of their own bicycles down a city street as fast as they could go—with a third wheel attached in front. The wheel was mounted flat on the handlebars. It spun freely, with two metal plates on top of it. One plate was flat, and the other was curved. This setup allowed the Wrights to measure air resistance, another key to building an airplane that would work.
