 Klein produced his first bicycle frames whilst a student at the Massachusetts Institute of Technology during the 1970s, and full production runs of frames began in the 1980s. In 1995 the company was purchased by the Trek Bicycle Corporation, and the original Klein factory at Chehalis closed in 2002 as production moved to the Trek headquarters at Waterloo. Widespread distribution in the United States stopped in 2007, and ceased altogether in the rest of the world in 2009.
