In 2008, Juang established Yiruite and developed the world's first electric skateboard "Raldey Boards". In recent years, Juang has quietly worked in the electric skateboard industry. In late 2015, hub motor electric skateboards started becoming popular in the U. S., and several American companies specializing in sports products came to Juang to discuss cooperating. Their brand image and product positioning coincided with Juang's philosophy. Both parties wanted durability and stability, as well as the safe and stable performance. They also wanted the parts to be made of the highest quality materials with an artistic appearance. Juang soon began to provide OEM services to those American brands. The e-boards that Juang produced were well designed and had excellent build quality.
