About Us

ROOTED IN
HUMBOLDT

Our workshop is more than a repair shop—it's a hub for the local cycling community. Whether you're tackling the fire roads of the Redwood Coast or commuting through Humboldt County, we ensure your machine is ready for the journey.

We believe in transparency, craftsmanship, and building lasting relationships with every rider who rolls through our doors.
