GT has been making 24” dirt bikes longer than most bike companies, and the Stomper Prime 24" packs years of off-road knowhow into a perfectly sized junior mountain bike. Built around a lightweight GT aluminium frame featuring GT's signature LegitFit system geometry, this bike boasts narrowed pedal positions, an adjusted center of gravity, and improved ergonomics to make balancing and pedalling intuitive. Equipped with a 50mm front suspension fork to soak up trail bumps, a 7-speed drivetrain with twist-shifting for effortless gear changes, and grippy Kenda Small Block Eight tyres, the Stomper Prime 24" gives young riders the performance, control, and confidence needed to stomp local dirt trails, gravel tracks, and bike paths.

Front Suspension Fork: 50mm travel All Terra coil fork absorbs trail bumps, rocks, and rough surfaces for increased control.
7-Speed Drivetrain: Intuitive 7-speed twist shifter allows young cyclists to master gear changing easily on climbs and flats.

Ergonomically Designed for Kids: The LegitFit geometry makes mounting, balancing, and pedalling significantly easier than standard youth bikes.
Great Trail Progression: Perfect for kids aged 7 to 11 years old (height range roughly 127 cm to 142 cm) ready to explore off-road trails and multi-gear riding.
Smooth Comfort on Rough Ground: The 50mm suspension fork cushions landing impacts and rough terrain to keep rides smooth and fun.
Child Has Outgrown 24" Wheels: If your rider is taller than 145 cm or older than 11, a 26-inch wheel model will offer a better long-term fit.
Looking for Disc Brakes: If you require hydraulic or mechanical disc brakes for heavy mud riding, step-up models like the Stomper Ace may be preferred over rim V-brakes.
