Marin San Quentin 20" Kids Bike - 2026
- SR Suntour XCM Suspension fork
- Tektro hydraulic disc brakes
- Shimano 8-speed gears
The Marin San Quentin 20 Kids Bike – 2026 is a scaled-down version of Marin’s renowned hardcore hardtail, built to offer young riders real mountain bike performance. With a tough aluminium frame, 80mm suspension fork, wide 2.6” tyres, and kid-specific hydraulic disc brakes, it’s equipped for speed, control, and serious off-road fun.
Key Features and Benefits:
- Series 2 6061 aluminium frame with 20” wheels: This frame uses the same durable material found in adult hardtails, offering high strength with low weight. This gives young riders a tough yet agile platform for trail riding.
- SR Suntour XCM 24 BOOST fork with 80mm travel: The front suspension absorbs bumps and rough terrain, improving traction and comfort. The result is a smoother ride with more control and confidence.
- Tektro HD-J285 hydraulic disc brakes with short-reach levers: Designed specifically for children’s hands, these brakes provide strong and reliable stopping power. This ensures responsive braking in all weather, increasing safety and control.
- Shimano Altus 8-speed drivetrain with 11-32T cassette: A wide gear range makes it easier to tackle climbs and control speed on descents. This allows kids to adapt to varied terrain without struggle.
- Wide 20 x 2.6” Vee Tire Crown Gem tyres: These tyres offer extra grip and stability on dirt, gravel, and roots. This gives riders the traction needed to stay upright and in control.
- Forged alloy crankset with narrow-wide chainring: The chainring design reduces the chance of dropping the chain, while the shorter 140mm crank arms suit smaller legs. This makes pedalling smoother and more efficient.
Built for young riders who want a proper bike, the San Quentin 20 delivers capable trail performance in a size that fits. The tough frame, real suspension, and reliable components provide the control, grip, and confidence kids need to ride harder and progress faster. It’s not a toy – it’s a trail-ready machine.
Give them the right tools to ride with control and confidence on real terrain. The Marin San Quentin 20 is ready for the next step.
