VIS is not only a vehicle, but also an emotional partner of its users. After connecting via Bluetooth, users can download custom information from the cloud server and select the emoticon package representing their mood to be displayed on the electronic screen powered by solar energy. This makes it a customized private shared bicycle. The product follows the rule of simple design, i.e. every detail has its value. The smooth U shape and bright color give a young and interesting impression. The U-shaped frame also reduces the height, making it easier to get on and off, which ensures a comfortable riding experience
