The Donald Duck bikes were introduced in three sizes; 20″, 24″, & 26″ in both boys and girls models. These bikes were made under license from Disney studios and were made until about 1951. The 26″ bikes are, by far, the rarest of these bikes. Only a handful of originals are known. The duck head on a 26″ bike is mounted on the front fender insread of the head tube and is a totally different piece than the smaller bikes.
