Trek's journey began in 1976 when founders Dick Burke and Bevil Hogg, fueled by a shared passion for cycling, set out to create a brand that went beyond the ordinary. Starting in a southern Wisconsin barn, Trek emerged with a mission to craft extraordinary bikes. Born out of a culture of craftsmanship and rebellion, Trek challenged the convention that only European bikes could be great. Today, Trek stands as a symbol of relentless progression, innovation, and a commitment to building bikes that people love.
