OTSBO is a multi-functional transformable toy with 6 different configurations. It is a first approach product for kids to the world of skateboarding. In it's first configuration kids from 18 months can be walked by their parents using the extension stick in the back. In the second step it is used as a ride-on toy. Following that the seat is removed and it converts into a scooter-like with three different heights. At this stage kids start to realise that they can curve by putting their wight on the sides of the board. Eventually all the accessories are taken off and it used as a mini longboard.
