24-Inch 7-Speed Kids Mountain Bike

Built for the Trail. Sized for the Rider.

The 24-inch kids mountain bike is built for riders ages 8 and up who are ready for real terrain. A high-carbon steel frame in matte black with neon green rims gives it unmistakable trail-ready style, while a 7-speed Shimano-style derailleur with twist shifter lets kids tackle hills and flats without fighting the gears. The front suspension fork absorbs bumps on gravel, dirt, and pavement. Dual hand brakes — one on each side — give confident, responsive stopping power. Seat height (28.5–34.5") and handlebars (38–40") are both independently adjustable so the bike grows with your rider from 56" to 66" tall. Ships 85% pre-assembled. ASTM and CPSIA compliant.
