• 【Powerful Motor】With a 500w brushless gear motor, it can reach a maximum speed of 35-40KM/H. Compared to brush motors, it allows for smooth and low noise operation without replacing the brush, thus making maintenance easier. The display and pedal sensor will allow you to quickly switch between throttle control, cruise control and pedal assist sensor (PAS) to enjoy feeling the headwind on the road. 【LCD Display】The LCD meter with a color screen can display the real-time speed, maximum speed, average speed, total mileage, single mileage, battery power, assist gear/speed grading, cruise control, and error code, allowing you to grasp the usage status of the product. Meanwhile, the backlight enables you to see the screen clearly in a dim environment. 【Excellent Performance】The high efficiency (82%) can save you a lot of electricity. Moreover, the brushless gear motor produces low noise when used, which can create a quiet environment for you. It senses the rhythm of the pedal and adjusts the speed of the motor accordingly. This helps on long trips and avoids wrist pain caused by constant pressure. 【Safe and Reliable】The powerful FOC sine wave controller is conducive to ensuring the smooth operation of other parts, making your entire process safer and easier. Besides, the power-off brake handle can cut off the motor power in case of emergency braking so that the bike can stop in time and reduce potential safety hazards. 【Labor-saving】You don't have to pedal your bike laboriously anymore with this product and only need to gently rotate the turner to control the speed flexibly, which is very labor-saving and convenient. The adjustable five gears can bring you an unprecedented riding experience.
