Giant STP 20 FS 2026 - Kids Bike

- Fork: SR XCT Jr coil suspension fork with 63mm travel
- Drivetrain: microSHIFT Advent 1x8-speed drivetrain with youth-friendly shifter
- Brakes: Hydraulic disc brakes with lighter lever feel for smaller hands
- Wheels: 20in wheels with Kenda Amrak 2.2in grippy off-road tyres
- Standout: Youth-specific fit with shorter cranks and smaller cockpit
- Finance: Available with 0% APR finance
The STP 20 FS is built for kids who are ready to take their riding beyond the playground. Its low standover height and compact frame help keep balance easy and confidence high, especially for riders around 110–130cm tall.
Front suspension takes the sting out of roots, bumps and rough ground, making trails feel less intimidating and more fun. The short wheelbase and playful geometry encourage kids to lean into turns, lift the front wheel and experiment with movement on the bike as their skills develop.
Youth-focused components make a real difference. Shorter cranks suit smaller legs, narrower bars improve control, and hydraulic disc brakes are tuned for lighter riders, giving smooth, predictable stopping without needing lots of hand strength.
Strong 20-inch wheels and wide tyres add grip and stability on dirt and loose surfaces, while the simple 1x drivetrain keeps gear changes easy to manage. It’s a bike designed to help young riders progress, explore and enjoy riding off-road with confidence.
