Giant was established in 1972 in Dajia, Taichung County in the nation of Taiwan (now part of Taichung City), by King Liu and several friends. A major breakthrough came in 1977 when Giant's chief executive, Tony Lo, negotiated a deal with Schwinn to begin manufacturing bikes as an OEM, manufacturing bicycles to be sold exclusively under other brand names as a private label. As bike sales increased in the U.S., and after workers at the Schwinn plant in Chicago went on strike in 1980, Giant became a key supplier, making more than two-thirds of Schwinn bikes by the mid-1980s, representing 75% of Giant's sales. When Schwinn decided to find a new source and in 1987 signed a contract with the China Bicycle Company to produce bikes in Shenzhen, Giant, under new president Bill Austin (formerly vice-president marketing at Schwinn), established its own brand of bicycles to compete in the rapidly expanding $200-and-above price range. In 1984, Giant also set up a joint venture, "Giant Europe", with Andries Gaastra of Dutch bicycle manufacturer Koga-Miyata. In 1992, Gaastra sold his shares back, and Giant became a full shareholder of Giant Europe.
