The 2021 GT Jr Performer 18" BMX Bike is designed as a bridge between the popular 16" and 20" bikes sizes for younger riders continuing their venture into freestyle BMX, or just needing a bike to ride around the neighborhood. Traditional components such as loose ball bearings for the headset, bottom bracket, and hubs make maintenance easy and create less friction so that the bike isn't actively working against the rider. 3-piece cranks and modern gearing make sure that the rider feels right at home at the skate park. The GT Jr Performer 18" will provide tons of fun.

Awesome Bike! My 6 year old is super stoked. Went from a spider-man kiddie bike to this beauty. Rides great, and will last him for some years as he grows into it. Looking forward to seeing his start to rip it at the local track.

Not a transition from 16 to 20”. Bars are to wide seat is non adjustable for tilt so the kid can’t hardly sit on it. The cranks and the chainring are to long for little kids. The only thing small are the wheels. He likes his sisters specialized rip rock 20 with adj seat shorter cranks bigger chainring.
