Description

The Kellys NAGA Air Belt is built for kids ready to ride faster, smoother, and more confident. With a superlight aluminum frame and a belt drive system, this bike keeps things simple — no grease, no noise, and barely any maintenance. 


What makes this bike stand out is the automatic 2-speed internal hub. As your child rides, the bike shifts for them. No buttons, no confusion, only steady momentum whether they’re starting off or picking up speed.

Paired with Schwalbe tires and reliable Tektro V-brakes, the ride feels controlled, stable, and capable on pavement or light dirt. Every part of this bike is designed to help kids push a little further each time they ride. 

This is the next step forward! Less maintenance for you, and more freedom for them to explore, grow, and chase what’s ahead.

*This bike includes a $50 flat rate shipping fee

Ryan Q. ★★★★★

The belt drive is honestly the reason we switched — no chain grease on pants or hands, and it rides whisper quiet. My son's been out on it every afternoon since it arrived, and the aluminum frame is light enough that he can lift it onto the rack himself. It just feels like a proper upgrade from his

Emily ★★★★★

My kid took to this bike immediately, and the aluminum frame is so light they can actually lift it onto the rack themselves. The belt drive makes for a totally silent ride, which means I can hear them coming instead of guessing from the chain noise.

Mia ★★★★★

The belt drive is seriously low-maintenance, which I appreciate after years of greasy chains, and the superlight frame makes it easy for my kid to lift and steer. It rolls so smoothly that he's actually asking to go on longer rides now, and that alone was worth the money.
