Features1Durable: The panel is made of ABS material, which is light, sturdy and durable, with fine workmanship, good toughness and waterproof performance, providing better protection for the internal circuit and making it more durable. 2Good Heat Dissipation: The brushless controller adopts groove design, which has good heat dissipation performance and can protect the inner circuit to avoid thermal overload. 33 Mode Operation: When the motor hall is functioning normally, it automatically operates in sine wave mode. If one motor hall is damaged, it can automatically identify and repair the issue. When all motor halls are damaged, it switches to hall less mode. It remembers the phase sequence when the motor hall is in a normal state, ensuring error free operation even if halls are damaged. 4Smooth Operation: The sine wave brushless controller ensures smooth operation, offering a comfortable and enjoyable riding experience. 5Main Uses: For DIY electric bicycles, electric scooters, electric bikes, etc. Easy to maintain, electric bike brushless controller kit greatly improves the fun of riding, suitable for cyclists who like challenges.SpecificationItem Type: Electric Bike Brushless Controller KitMaterial: ABS, Aluminum AlloyWeight: Approx. 502g / 17.7ozPower: 1000WCurrent Limit: 38APackage List1 x Panel1 x Controller1 x Manual
