Marin Bikes' journey began in 1986, at the very heart of the mountain bike revolution in Northern California. Founded with a dedication to enriching the lives of riders, the brand emerged from a culture of hard work and an obsession with the trails of Mt. Tamalpais. While others focused solely on racing, Marin focused on the experience—creating high-caliber bicycles designed to be playful and provide years of riding enjoyment. Today, Marin stands as a global influencer, blending its storied heritage with modern performance to ensure that every model is, above all else, made for fun.
