With the acceleration of people's life rhythm and the continuous expansion of the scope of activities, people hope to obtain a light, fast, simple and safe means of transportation. Electric bicycles are generally welcomed by consumers because they are light and fast, and meet the needs of modern people in pursuit of environmental protection, efficiency, and safety. In this regard, SCT has launched an electric bicycle controller solution with functions such as overcurrent, overvoltage, locked-rotor, and current-limiting protection.
