In December, 1975, Richard (Dick) Burke and Bevil Hogg established Trek Bicycle as a wholly owned subsidiary of Roth Corporation, a Milwaukee-based appliance distributor. In early 1976, with a payroll of five, Trek started manufacturing steel touring frames in Waterloo, Wisconsin, taking aim at the mid to high-end market dominated by Japanese and Italian made models. Trek built nearly 900 custom hand-brazed framesets that first year, each selling for just under $200. Later that same year Trek Bicycle was incorporated. In 1977, Penn Cycle in Richfield, Minnesota became the first Trek dealer in the world. Within three years, Trek sales approached $2,000,000.
The relationship between Trek and Tour-de-France winner Greg LeMond went back to at least 1995 when LeMond licensed Trek to produce LeMond branded bicycles. According to Trek, "In 1999, the LeMond line was one of the fastest growing road bike brands and one of the top five largest road bike brands in the United States".
In March 2008, LeMond Cycling Inc prepared a suit against Trek, accusing it of bowing to pressure from "third parties" to "wind down" his brand through lack of distribution and promotion, especially in the European market. The complaint also says that "Since 2001, Trek has systematically sought to silence Mr. LeMond's right to make comments that constitute an informed and honest opinion on matters of legitimate public interest – the problems associated with the use of performance enhancing substances". The complaint includes examples of Trek threatening its ties with LeMond in 2001 and 2004 after he made public statements against doping, Michele Ferrari, and Lance Armstrong.
Trek responded in April 2008 by suing to sever business ties with LeMond. Trek's press release said that "LeMond's suit was characterized by Burke as containing false and irresponsible allegations". Burke also said "for years, Greg LeMond has done and said things that have damaged the LeMond brand and the Trek brand as a whole". . . . "His actions are inconsistent with our values—values we believe in and live everyday. And after years of trying to make it work, we are done." The suit was settled out of court in 2010.
