PART OF THE FAMILY. Out there, a great adventure awaits. Cycling is the first step towards independence, and the bike is not just an object; it is the best friend, the 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 redesigned. Lightweight aluminum frames, child-friendly components, and technical details tailored to a child's anatomy are utilized.
