Handle made of ABS plastic. With prolonged use, the sensitivity of the throttle knob decreases. Sometimes the spring inside the throttle breaks, so that the throttle can no longer stay in place. If your scooter beeps and won’t start , you can fix the fault here.
The connector for the throttle knob is behind the dashboard. A set of hexagonal wrenches and a screwdriver will suffice for replacement.

When do I need to replace the accelerator (throttle lever) on my Xiaomi 4 scooter?

Here are the main reasons why you may need to replace the accelerator (also known as the throttle lever) on your Xiaomi 4 electric scooter:

1. Error 14 (Error 14) in the Dashboard:

   Xiaomi 4 models directly display Error 14 on the dashboard (screen) when a problem is detected with the accelerator sensor (Hall sensor). This is the clearest sign that the accelerator needs to be checked or replaced.

2. Physical Damage: breakage (e.g. after a fall), crack, severe mechanical wear, loose or broken components.

3. Accelerator Malfunctions:

   Stalling: the accelerator stalls, has difficulty turning or does not return to its original (free) position.
   Unresponsive: The scooter is completely unresponsive, very unresponsive or intermittently/jerkily responsive to the accelerator.

4. Preventive Replacement/Upgrade: After an Accident/Fall,even if the accelerator appears intact externally.
