oops sorry for responding late.
That wooden vehicle was made by the natives of the mountain city of Baguio. These natives are called the Igorots.
Another mountain tribe, the Ifugao's, are really creative:
These mobile contraptions were once created to serve a need. The men-folk were having a difficult time going to and from their homes to their muyongs up the mountains, often bringing home firewood and crops tended up there. It would often take them hours to walk the distance and carry the load.
This then gave birth to the first scooter. They would push it up the hills and work for the day. Firewood would be strapped along both sides of the scooter and other goods tied at the back.
The ride back home would then be a breeze.
These vehicles are fashioned out of wood, minimizing the use of nails. Through time the simple device to ferry firewood and tubers soon became art, their designs and styles becoming more intricate and complicated.
