Siren Bicycles

Forged in the heat of a steel furnace high in the Rocky Mountains, Siren Bicycles are race-proven and made for the adventurer inside you. Our bicycles have carried riders across the American Continental Divide, taken endurance racers to countless podiums, and allowed weekend adventurers to reach the edge of their personal frontiers. Whether you're seeking a racing machine or pure dirt-trail discovery, Siren Bicycles are designed for what's inside you.

American labor and materials guarantee that every Siren Bicycle is built to go the distance. From hand-shaped tubing for the legendary John Henry to the Tour Divide mastery of the Siren Song; from the jaw-dropping beauty of the Siren Twinzer to the cutting edge geometry of the Siren 55: you don't just get a frame, you get our heart and soul. Take it and make your next ride the best one ever.

You want to ride. We want to take you there!
