We took our Matt Jones-inspired Marin San Quentin and shrunk it down to fit 24” wheels. It's the perfect bike for kids who are ready for their first proper, hardcore hardtail mountain bike.

The Marin San Quentin 24”, 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 24” will feel just like a ‘grown up’ mountain bike to your little ripper, built with a stout Series 2 aluminum frame, 24” wheels, an RockShox suspension fork, 9-speed microSHIFT drivetrain and kid’s specific hydraulic disc brakes.


San Quentin 24” and 20” both feature a Series 2 aluminum frame, with a tapered headtube, 3D forged dropouts, IS brake mounts, semi-internal cable routing and 135mm open dropouts.

Taking cues from the Alcatraz, as well as the full-size San Quentin lineup, the San Quentin 24” and 20” proved all the benefits of DJ style, with massive standover, slick frame tubes, and a hot paint job.

A slack headtube angle paired with a steep seat tube angle creates a ride that will fly uphill, yet descend like it’s on rails. The balanced rider position is puts the rider weight between the wheels for steady climbing and handling on flats, while the slack front end helps to add higher speed stability through turns and rough patches.

Modern 1x drivetrains, just like the larger San Quentins, give the rider the benefits of shifting simplicity and chain retention.
