Compatible with all two-wheeled vehicles on the market: (The original vehicle controller uses an 8+16+6 socket outlet). Scan the QR code with WeChat and follow the voice prompts. Simply squeeze the brake and press the three-speed buttons to automatically select the corresponding function. No wiring required, and installation is complete in three minutes. Customizable functions such as fast/speed limit/soft start/hard start/electronic brake are available. Compatible with all vehicle models and voltages. Superior to other Bluetooth controllers, which are still divided into 1, 2, 3, 4, and 5 types, our product is a 5-in-1 controller, meaning you get five types of controllers for one price, allowing you to use them even after upgrading your vehicle. It also uses high-end components and accepts universal voltages of 48, 60, 72, and 84V. Vector Variable Frequency Sine Wave Controller: Controls motor speed and torque by controlling the motor frequency. It does not increase current, so it has no impact on the motor or battery. Advantages: High torque and high efficiency. Optimize the use of high-quality, brand- components. Cheap controller: The internal circuit boards and MOSFETs are recycled. Although the controller is inexpensive, the quality and consistency are poor, resulting in a high failure rate and a short service life. Brand- imported chip: The 64-bit chip uses advanced algorithms, providing better protection for the MOSFETs and higher current efficiency. Brand- MOSFETs and other electronic components are manufactured without cutting corners, resulting in lower heat generation, a lower failure rate, and a longer service life. "Five-in-one, fully universal, fully intelligent, no-break wiring." The imported 64-bit main chip is compatible with all two-wheelers and can be installed simply by following the voice prompts.
