Fuel EX Jr is the real deal: a mountain bike designed for kids. It's modelled on the Fuel EX line, with full suspension tuned for lighter riders, a lower bottom bracket and shorter reach for better control, and a kid-specific geometry that'll get more young riders out on the trails. The sizing of this bike is perfect for kids 146-160 cm/58-63˝ tall.

It's right for you if...

Your kid has MTB dreams that are as big as the mountains they're riding. They're serious about mountain biking, but not quite big enough for an adult Fuel EX. Maybe they're lucky enough to have a NICA league at their school, or maybe you're an avid mountain biker and you want your kid to enjoy the trails with you.

The tech you get

A lightweight and strong Alpha Gold Aluminium frame, X-Fusion Performance Suspension tuned for lighter riders and a quality Shimano Deore drivetrain to help young riders tackle varied terrain. This kids' MTB has the same tech as the adult version, including ABP, Full Floater, Evo Link and suspension lockout. It also has a kid-specific saddle and hydraulic disc brakes for comfort and control.

The final word

Fuel EX Jr is our highest-performance mountain bike for kids, and our only kids' full suspension bike. It's not just a small adult bike – it's a bike built from the ground up with a kid-specific geometry that's based on an adult frame and a performance spec that'll have your kids dominating the trails in no time.
