Features1ABS Material: The panel made of ABS material, ensuring lightweight, durability, and water resistance. Its fine craftsmanship and rugged design provide enhanced protection for the internal circuitry, making it highly durable. 2Heat Dissipation and Overload Protection: The controller's metal shell features a groove design that provides effective heat dissipation, protecting the internal circuitry from overheating. 33 Mode Operation: When the motor hall sensors are functioning properly, it automatically operates in sine wave mode. In the event of damage to one hall sensor, it automatically detects and repairs it. If all hall sensors are damaged, it switches to non hall sensor mode. The system also remembers the motor's phase sequence in normal conditions, preventing errors in case of hall sensor damage. 4Compatibility: Designed for 36V 48V electric bikes, this kit provides compatibility with a wide range of voltage options. Its versatility allows for easy integration with various electric bike models. 5Powerful Performance: With a 500W output and 28A current, this brushless controller kit delivers impressive power and performance. It significantly enhances the performance of your electric bike, providing a smooth and reliable ride experience.SpecificationItem Type:ElectricBikeControllerKitWeight: 734g/25.9ozMaterial: ABS and aluminum alloyPower: 500WCurrent Limit: 28APackage List1 x HalfTwistThrottleGripwithPanel1 x HalfTwistThrottleGrip1 x Handle Grip2 x Key1 x Accessories1 x Controller1 x Instructions
