The Yepp Bolder is a children’s wagon designed in the final bachelor course at the Delft University of Technology at the faculty Industrial Design Engineering. This project is a cooperation between the University and the company GMG. GMG’s main business is selling bicycle seats for children under a brand called Yepp. During this project I investigated market opportunities for the company. Although the children’s wagon market is quite small worldwide, in the Netherlands and Germany children’s wagons are quite common. During my investigation I found some interesting facts about the children’s wagon and took this as an opportunity to design an innovative children’s wagon for GMG.
