Designed in conjunction with Marin ambassador/MTB legend Matt Jones, the Marin Alcatraz collection is ready for dirt jumps, pump tracks, skateparks, slopestyle, or virtually anything you throw at it.
We've taken the Alcatraz 1 and scaled it down for smaller riders. Built upon the same tubing as the larger models, it features a 360mm reach, 69° headtube angle, and 72° seattube angle, with 369mm chainstays. A suspension-corrected rigid CrMo fork is designed to handle rough-and-rowdy riding, and a simple and stout single-speed drivetrain and Tektro mechanical disc brakes ensure a fun and safe ride.
Sunset Cycles offers the 2025 Marin Alcatraz 24 kids' dirt jump bike in Yellow Fade finish with up to 24 months 0% finance and free delivery.
