Meet the new Belter 20 Auto

The Belter 20 Auto features a lightweight aluminum frame with updated geometry for greater stability and agile handling. The low-maintenance 12mm belt drivetrain pairs with a Sturmey Archer 2-speed automatic rear hub, delivering smooth, gear-free shifting that adapts to the rider's pace. Sliding dropouts, sealed bearing 20" wheels, and Schwalbe Billy Bonkers 2.0" tires ensure a durable, confident ride. Smaller chainring diameters and kid-optimized gearing make this the ideal next step for young urban riders.

next generation

I use bikes since I was 6. I have an old nexus gear mecanism for daily riding in Bucharest. I enjoy it!

But I notice I have a little envy looking at my son, how he rider his new Belter. His first free ride was when he was 2 and 7 months old. :))

Belter Auto 20

My kid LOVES this bike! He asks to go riding every day after school since upgrading from his old 16” SE bike. As a result, I ordered my soon to be 2 year old a matching 12” balance bike as he loves his current Stryder balance bike next to his big brother. Early Rider just earned a new lifetime customer!
