Why is my Harley slow?

1. The speed limit line is connected, causing the electric vehicle to accelerate slowly: After some users purchased an electric vehicle, the speed limit line was not disconnected, and the result was that the electric vehicle accelerated slowly and ran weakly. However, this is a normal phenomenon and is designed by the manufacturer for safety and meeting standards. Therefore, it is easier to solve this situation, which is to disconnect the speed limit line to make the electric vehicle go faster.
?2. Battery aging leads to slow acceleration of electric vehicles: Battery aging is relatively common. Everyone knows that batteries have a certain number of charges and discharges. When they are overused, they will age, which will directly lead to a decrease in the battery’s acceleration performance and insufficient power. Therefore, the general solution for this situation is to replace the battery with a new one.

?3. The controller and motor do not match, resulting in slow acceleration of electric vehicles: In addition, some users think that the speed of electric vehicles is only related to the quality of the battery. In fact, this idea is wrong. In fact, the speed of electric vehicles is also related to the controller and motor. Why do you say that? Because the speed of an electric vehicle is determined by the speed of the motor, and the motor speed is associated with the controller, when the controller does not match the motor, it will affect the speed of the motor, resulting in slow acceleration of the electric vehicle.
?4. The speed control knob is faulty, causing the electric vehicle to accelerate slowly: This is the most easily overlooked situation, because few people would think that the speed control knob causes the electric vehicle to accelerate slowly. Why does the speed control knob also cause electric vehicles to accelerate slowly? In fact, this is not difficult to understand. If the speed control knob fails and the user turns the knob to the end, it will only have the same effect as twisting the original knob by half. Therefore, electric vehicles may accelerate slowly.
?5. External resistance causes electric vehicles to accelerate slowly
