PART OF THE FAMILY. Out there, a great adventure awaits. Riding a bike is the first step towards independence, and the bike is not just an object, but a best friend, a big brother, a part of the family. From the 10" balance bike to the 26" bike, KTM Kids Bikes are loyal companions. For 2021, the entire range has been completely reworked. Lightweight aluminum frames, child-friendly components, and technical features tailored to the anatomy of children have been implemented.
