ST-One is a 20-inch shaft-drive foldable intelligent e-bike. It was developed to provide a short-distance travel tool for urban users. The whole vehicle is composed of less than 10 modules. It replaces the traditional chain drive with a maintenance-free shaft-drive design, giving users a much smoother and safer riding experience. The built-in smart sensor detects the riding terrain in real time and adjusts the power output accordingly. With the introduction of a pressure casting technique, the vehicle is more impact-resistant and stronger. It was designed for easy manufacturing and easy maintenance while reducing the waste of raw materials.
