Decoding Common E-Bike Errors

E-bikes are an incredible way to commute, explore, and enjoy the outdoors. However, like any machine, they can encounter technical issues. Understanding these common e-bike errors can save you time, money, and frustration. This guide will help you understand what those error codes mean and provide step-by-step solutions to get you back to enjoying your ride. We'll break down everything from undervoltage issues to motor faults.

Understanding Fault Codes: A Quick Reference

Here’s a breakdown of common error codes and troubleshooting steps for your Riding Times e-bike:

1. E06: Undervoltage Protection

• Cause: The battery voltage is lower than the minimum required, or the battery is damaged.
• Solution:
  1. Charge the battery completely.
  2. If charging doesn't resolve the issue, the battery might be damaged and need replacement.

2. E07: Motor Hall Fault

• Cause: A break in the motor wiring or a damaged Hall sensor within the motor.
• Solution:
  1. Inspect the motor wires for any damage or loose connections. Check the Hall terminals on the controller (usually six wires in a black terminal) to ensure they are securely connected.
  2. If the Hall sensor itself is faulty, consider replacing the motor. Contact Riding Times customer support to discuss options for motor replacement.

3. E08: Motor Phase-Wire Short Circuit or Controller Fault

• Cause: Shorted or damaged motor phase wires, or internal damage to the controller.
• Solution:
  1. Check the motor phase wires (usually yellow, green, and blue) for any signs of damage or exposed wires. If damaged, replace the motor.
  2. Power off your e-bike and unplug the controller phase-wire connectors. Then, power it back on. If the error code disappears temporarily but returns, the controller might be faulty and require replacement.

4. E10: Instrument/Controller Communication Fault

• Cause: The display (instrument) and the controller aren’t communicating properly.
• Solution:
  1. Check the communication wires between the instrument and the controller for damage and secure connections.
  2. Inspect the rear-wheel motor wires. Damage here can sometimes affect the controller, requiring both motor and controller replacement.

5. E11: Throttle Twist-Grip Fault

• Cause: A problem with the throttle connection or damage to the throttle itself.
• Solution:
  1. Ensure the throttle twist-grip wire connector is securely connected and not loose.
  2. If the connection is good, inspect the throttle twist-grip and its wiring for any visible damage. Replace the throttle if needed.

6. Unable to Power On

• Cause: Issues with battery installation, the power switch, or the combination switch.
• Solution:
  1. Make sure the battery is properly installed, the key is securely locked, and the weak-power switch is turned on.
  2. Check the combination switch and instrument for any damage. Also, check the connectors of the instrument communication wires and combination switch wires.

7. Motor Does Not Rotate When Turning the Throttle Twist-Grip

• Cause: Throttle issues, incorrect power settings, or brake lever interference.
• Solution:
  1. Check the throttle twist-grip and wiring for damage.
  2. Press the power-on key three times in a row to switch between power, assist, and electric modes.
  3. Make sure the brake levers aren't damaged and that the brake lights turn off when the levers are released.
  4. If the internal air-cooled rear wheel of the motor does not rotate, replace the clutch if the internal clutch gears of the motor are damaged.

8. Abnormal Motor Noise

• Cause: Brake misalignment or internal motor damage.
• Solution:
  1. Adjust the brakes if they are rubbing and causing noise.
  2. If there is abnormal noise inside the motor, the motor clutch gears may be damaged. Replace the motor clutch or motor core.

9. The Motor Lacks Power When Riding Under Load

• Cause: Problems with motor phase wires or a faulty motor core.
• Solution:
  1. Ensure the motor phase-wire connectors are connected properly, and the motor phase wires aren't damaged.
  2. If the motor is still underperforming, replace the motor.
