SAN QUENTIN 20

The San Quentin 24 and San Quentin 20 are for the riders growing up at the local bike park and crusing around the neighborhood that want a kid-size bike with adult-size performance.

We took our Matt Jones-inspired Marin San Quentin and shrunk it down to fit 20” wheels. It's the perfect bike for kids who are ready for their first proper, hardcore hardtail mountain bike.

The Marin San Quentin 20”, just like the big kid’s version, shreds the boundaries of the mountain bike genres - doing it all with a huge splash of big air, speed and style.

Designed with the input of freeride legend Matt Jones, the San Quentin takes the DNA of our dirt-jumping Alcatraz and mutates it into a go-further and faster all-round, hardcore hardtail. The San Quentin 20” will feel just like a ‘grown up’ mountain bike to your little ripper, built with a stout Series 2 aluminum frame, 20” wheels, an SR Suntour XCM suspension fork, 8-speed Shimano drivetrain and kid’s specific hydraulic disc brakes.
