We wear a push rod and take a walk with a guardian.  As I rub it by yourself, as a normal tricycle with the pushbars removed.  Furthermore, it removes one pedal and one rear wheel and also has a running motorcycle form.  By rearranging according to the degree of growth, three ways of enjoying can be done with one unit.  I can not ride a tricycle yet, I am a little worried about putting it by myself ... At times such as when wearing a push rod I can safely control the traveling speed etc of the guardian.  When you can ride a tricycle by yourself, you can use it as a normal tricycle by removing the pushing stick.  If you remove one pedal and rear wheel, it changes to a sporty running motorcycle.  Ideal for cultivating a sense of balance to ride a bicycle.  ※ When using as a running bike, be sure to wear protective gear such as helmet and use it in the place where the guardian confirmed safety (helmet is not an accessory).
