1、Durable Material: The panel is made of premium ABS material, lightweight yet durable, with waterproof and excellent toughness. It provides better protection for the internal circuit and enhances durability. 2、Efficient Heat Dissipation: The controller shell is made of metal with a grooved design, offering excellent heat dissipation. This effectively protects the internal circuit and prevents overheating. 3、3 Mode Operation: When the motor hall is working normally, it automatically runs in sinewave mode. In case one hall is damaged, it will be identified and repaired automatically. If all halls are damaged, it switches to hallless mode. It remembers the phase after identifying the phase sequence in normal hall state, and there will be no errors when the hall is damaged. 4、Accurate Control: The brushless controller adopts advanced technology, ensuring stable and accurate control of the electric bike. It provides precise speed and power adjustment, enhancing the overall riding experience. 5、Easy Installation: The controller kit is designed for easy installation. It can be easily integrated into your electric bike system, saving you time and effort.
