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 the best friend, the big brother, a part of the family. From the 10" balance bike to the 26" bike - the KTM Kids Bikes are loyal companions. For 2021, the entire range has been completely redesigned. Lightweight aluminum frames, child-friendly components, and technical details tailored to the child's anatomy are used.
