Description
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
