kickstand
A kickstand is a device on a bicycle or motorcycle that allows the bike to be kept upright without leaning against another object or the aid of a person. A kickstand is usually a piece of metal that flips down from the frame and makes contact with the ground. It is generally located in the middle of the bike or towards the rear. Some touring bikes have two: one at the rear, and a second in the front.
==History==
The earliest known kickstand was designed by Albert Berruyer in 1869, and since then kickstands have been independently reinvented many times. It was mounted below the handlebars, so was much longer than more recent designs. A shorter model was patented by Eldon Henderson in 1926.〔 In the 1930s, a "smaller, more convenient" kickstand was developed by Joseph Paul Treen.
In 1891, Pardon W, Tillinghast patented a design for a stand which was mounted on the pedal, but folded up flat under the pedal when not in use.
Kickstands on bicycles fell out of fashion in the 1970s, as the bicycles became lighter, and many riders were concerned about extra weight.〔
