• Damaged motor phase
• Damaged motor cable
• Damaged controller cable
• Loose motor harness connection
• Damaged connector
• Worn cable
• Internal cable issue
• Damaged controller
• Damaged motor
• Hall sensor issue inside the motor
• Visible impact or connector damage

Troubleshooting Steps

Step 1 – Inspect the Motor, Controller, and Attached Cables

Turn the bike off before continuing.

Inspect the accessible:

• Motor cable
• Controller cable
• Motor harness connection
• Attached connectors

Check for:

• Loose connections
• Bent pins
• Worn cables
• Broken connectors
• Dirt or contamination
• Visible cable damage
• Impact damage

If yes – Visible damage is found

If no – No visible damage is found

Clean and fully reconnect the motor harness and controller connection.

Restart the bike and check whether the error remains.

If the issue clears

The issue was likely caused by a poor or loose motor connection.

Monitor the bike during future riding.

If the issue remains

Continue to Step 2.

Step 2 – Check Whether the Error Persists After Reconnecting

After reconnecting the motor harness and controller connection, restart the bike and test the motor carefully.

If yes – The E23 or E24 error still appears

The issue may involve the motor or controller system.

Please contact our support team with the photos/videos listed below so we can review the next step.

If no – The error no longer appears

The issue was likely caused by a temporary connection issue.

Continue monitoring the bike during use.
