Unleash your young shredder’s potential with the Marin San Quentin 24" Hardtail Children's Mountain Bike in a sleek Grey/Black finish—now available at The Rolling Fix, Liverpool’s go-to destination for quality bikes and expert service.
Inspired by freeride legend Matt Jones, the San Quentin 24" is not just a downsized version of a hardcore mountain bike—it is a hardcore mountain bike, purpose-built for kids ready to take their riding to the next level. Whether they’re hitting the local trails or sending jumps at the bike park, this beast delivers big-bike performance in a smaller package.
Built to Ride Hard
The San Quentin 24” boasts a Series 2 6061 aluminum frame, designed for strength, durability, and proper trail handling. Its modern trail geometry offers a slack head tube angle for confident descending, balanced with a steep seat tube angle for efficient climbing and control. The dirt jump-inspired frame design provides excellent standover clearance, stylish tube shapes, and eye-catching aesthetics pulled straight from Marin’s pro-level line-up.
Suspension and Control
Up front, the RockShox Judy Silver TK fork with 100mm of air-sprung travel smooths out rough trails while giving kids a responsive, adjustable ride. Matched with Tektro hydraulic disc brakes and kid-friendly levers, young riders get dependable stopping power in all conditions—perfect for building confidence on descents.
Simple Shifting, Big Gearing
The microSHIFT Advent 9-speed drivetrain delivers a wide 11-46T gear range, perfect for tackling climbs and hammering flats. The forged alloy crankset with a 30T narrow-wide chainring ensures excellent chain retention, even when the trail gets rowdy.
Ready to Shred
Rolling on 24” double-wall alloy rims and grippy Vee Tire Co. Crown Gem 2.6” tyres, the San Quentin 24” is trail-ready out of the box. The cockpit features Marin MTB riser bars, a short 35mm alloy stem, and Marin’s Kids MTB saddle, all dialled in for smaller riders.
