Abstract
A retractable stand for an electric vehicle is connected to an electric running motor. A one-way clutch is disposed between an output shaft of the running motor and a continuously variable transmission. Upon forward rotation of the output shaft, the one-way clutch idles and power is transmitted through the continuously variable transmission to a drive wheel. Upon reverse rotation of the output shaft, the one-way clutch transmits power to a first gear but not to the transmission. The reverse rotation is transmitted through a gear box to a main stand which extends to a park position. The main stand is normally biased through a pair of compression springs to a retracted position.
