    Marin 2026 San Quentin 24

    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, a Manitou suspension fork, Shimano CUES drivetrain and kid’s specific hydraulic disc brakes.
