Doppo 'High Plains Drifter'

Across the ages, to the mountains, to the city, to the depths of our hearts.

The Doppo "High Plains Drifter" is a bike that returns to the origins of mountain biking while being rebuilt for modern riders. Its riding experience combines the exhilaration of cutting through the wind in a vast field with a gentleness that evokes nostalgic memories.

Meticulously handcrafted in small batches in our Portland, Oregon workshop, this frame effortlessly blends classic style with modern functionality, evoking the feeling of your first bike ride while inspiring new possibilities for your next off-road adventure.

Inheriting the spirit of the "clunkers" born in Marin County in the early 1970s, this bike conveys the rugged and free-spirited style of early MTB, and is sure to be an eye-catcher in the city, on the mountain, and in your own sensibilities.

Enjoy the fun of rigid mountain biking again. Now is the time.
