About our Bikes

These are not the "mountain bikes" available from the tourist rental shops in San Francisco. These are well-maintained, high quality mountain bikes built for riding trails. They perform well on the road, but ditch the baskets, racks, smooth tires and tourist branding so they can comfortably navigate the twisty singletrack or scenic fireroads of Marin, Sonoma or Napa Counties like a local, while still getting you to and from the trail comfortably.

Our booking process is easy and automated, and our bikes are tuned and ready for you when you arrive, so you can get your adventure started.

Great riding and stunning scenery

Family and Kids rides available

Custom routes tailored to your ability

Jamie and I really enjoyed our mountain bike trip with Mark! The ride was exactly the challenge and experience we wanted for the afternoon after attending conferences!

Marin County, CAlifornia the birth of a sport

Marin County is the birthplace of the Mountain Bike. Back in the early 1970s a group of young men and women started riding their Klunker paperboy bikes up and down the fire protection roads in the county.  While some would argue they weren't the only (or even first ones) to start taking bikes up and down mountains, it was their modification of their cruiser bikes, adding of handbrakes and eventually derailleur and multiple gears that get them credit with the birth of the sport. Come ride the birthplace with mountain Bike SF.
