Continuous innovation and transformation are the guiding principles of big banks. Dahang has one of the best research and bicycle industry development teams, proposed by Dr. David, and has more than 100 patents, including 4,344,042 patents, 4 17856 1 4019/kloc-0, 40 patents. Dahang has more than 60 best 3DCAD software engineers, and applied for patents in 2005. Every year is the pace of innovation, which our friends and competitors can only envy. Simpler, lighter, faster and stronger: these are our constant design goals, and the following are only some patented technologies and special functions. Innovative vertical folding technology simplifies and speeds up the folding process. This is a brand-new "upward" folding concept car frame, instead of the traditional horizontal folding method of folding the car body frame in half.
