What Do Error Codes on E-Bikes Mean and How to Fix Them?
Electric bikes (e-bikes) are advanced machines with sophisticated electronics. While this technology makes them efficient and convenient, occasional error codes can appear on the display, signaling a problem. Understanding these codes is essential for diagnosing issues and getting your bike back on the road.
Here’s a guide to the most common e-bike error codes, their causes, and how to resolve them.
What Are Error Codes on E-Bikes?
Error codes are numeric or alphanumeric messages displayed on your e-bike’s screen, alerting you to specific issues with its components. These codes vary depending on the e-bike manufacturer, but they generally point to problems with the motor, battery, sensors, or wiring.
Common E-Bike Error Codes and Fixes
1. Error 01: Motor Connection Problem
- Cause: Loose or disconnected motor wires.
- Solution:
- Inspect the motor cables for damage or loose connections.
- Ensure all plugs are securely attached.
- If the problem persists, contact a professional for a thorough inspection.
2. Error 03: Throttle Malfunction
- Cause: A stuck or faulty throttle.
- Solution:
- Check the throttle for physical damage or dirt.
- Ensure it moves freely without sticking.
- If cleaning doesn’t help, the throttle may need replacement.
3. Error 05: Brake Sensor Issue
- Cause: The brake lever sensor is stuck or malfunctioning.
- Solution:
- Check if the brake lever is fully released.
- Inspect the sensor wire for kinks or damage.
- Adjust or replace the sensor if needed.
4. Error 07: Battery Voltage Problem
- Cause: The battery is overcharged, undercharged, or experiencing voltage fluctuation.
- Solution:
- Charge the battery to the recommended level.
- If fully charged, test the voltage with a multimeter.
- Replace the battery if it no longer holds a charge.
5. Error 10: Communication Error
- Cause: Faulty connection between the controller and display.
- Solution:
- Check the wiring between the controller and display.
- Ensure all connectors are clean, dry, and securely plugged in.
6. Error 21: Speed Sensor Malfunction
- Cause: The speed sensor is misaligned or damaged.
- Solution:
- Realign the speed sensor near the magnet on the wheel.
- Check for damage to the sensor or its wiring.

Further Troubleshooting Tips
- General Communication Errors (Codes 22, 30):
- Inspect connectors and cables for wear or corrosion. Poor connection can cause intermittent or total communication failure between components.
- Ensure all wiring is correctly connected and not pinched or frayed.
- Throttle and Sensor Errors (Codes 04, 05, 12, 25, 26):
- Many errors are linked to faulty sensors or physical obstructions in the throttle or cables. Checking and cleaning connectors, sensors, and cables is often a quick fix.
- Always confirm the correct sensor calibration if available.
- Battery Issues (Codes 06, 07):
- Both low and high voltage errors are common when the battery is old, improperly charged, or not securely connected. Testing the battery with a multimeter before further action is recommended.
- Motor Overheating (Code 10):
- If the motor overheats, check whether the motor is overloaded, obstructed, or subjected to prolonged use under high power. Cooling down and reducing stress on the motor should fix the issue.
