To change the motor clutch, you do not need to remove the flywheel, but you will need to remove the gear. If the motor shaft is difficult to disassemble, it's likely because it's already worn or damaged. In such cases, do not continue applying lubricant or forcing rotation, as it may make the clutch even harder to remove. If you could not remove it, please use a puller tool.

We recommend the following steps for customers:

Stop applying oil or trying to rotate the motor once a problem is noticed.
Wait for replacement parts to arrive before attempting further disassembly.

Question 7

Throttle Becomes Unresponsive – Troubleshooting Guide

Accepted Answer

The most common cause is a brake lever reset problem.

1. Inspect the Throttle & Cables

Accidentally turned off the throttle (press the power button three times in a row to turn the throttle off and on)
Check for visible damage on the throttle and cables.
Ensure all connectors are securely plugged in.
2. Check the Brake Light

If the brake light stays on without pressing the brake, unplug the left and right brake handle cable connectors one at a time.

3. Identify the Faulty Brake Handle

Unplug one brake handle cable at a time (do not unplug both at once, or the P gear won’t release).
If unplugging the left brake cable turns off the brake light, the left brake handle is faulty.
4. Adjust the Brake Handle Screw

Reconnect the brake handle cable.
Use a 2mm Allen wrench to tighten the screw (turn 1-2 times clockwise).
Observe the brake light—if it stays off, the issue is resolved.

5. Test the Throttle

Turn the throttle and check if the motor responds.
If the motor runs normally, the problem is fixed.
