Features1ABS Material Panel: Providing lightweight, sturdy, and durable construction. Fine craftsmanship ensures toughness and waterproof performance, extending its lifespan. 2Metal Housing for the Controller: Featuring a grooved design for better heat dissipation. This protects the internal circuitry and prevents overheating. 33 Mode Operation: When the motor hall is functioning normally, it operates automatically in sine wave mode. If one hall sensor is damaged, the controller will automatically detect and repair it. If all hall sensors are damaged, it switches to a hall less mode. The controller's memory retains the phase information when the hall sensor is in normal condition, ensuring error free operation even in case of hall sensor failure. 4Suitable for 36V and 48V Systems: Providing a power output of 500W and a current of 28A. This kit offers reliable control for various electric bike applications. 5Easy to Install and Use: This panel and controller kit provides smooth, efficient, and responsive performance for an enhanced electric bike riding experience.SpecificationItem Type:MotorControllerTwistThrottleGripWeight: 618g/21.8ozMaterial: ABS and aluminum alloyVoltage: 36V 48VPower: 500WCurrent Limit: 28ALow Voltage: 30V 42VPackage List1 x HalfTwistThrottleGripwithPanel1 x HalfTwistThrottleGrip1 x Grip1 x Accessories1 x Controller1 x Instructions
