When the controller is broken, the e-bike riding experience becomes unstable and full of challenges. You may encounter issues such as being unable to start, loss of electric assist, or abnormal battery drainage, which severely affect riding efficiency and safety. Ultimately, problems like motor overheating and display malfunctions could turn your ride into a "disaster."
Common Issues
Although controllers are designed to be robust, they can still encounter common problems over time:
1. Loss of Power
- Symptoms: The electric bike cannot accelerate.
- Causes: This may be due to the controller failing to transmit power to the motor, internal circuit faults, or insufficient battery charge.
- Impact: Loss of power directly affects riding comfort and safety.
2. Flickering Indicator Lights
- Symptoms: The controller indicator light frequently flickers.
- Causes: This typically indicates an internal fault, such as overload or short circuit.
- Impact: It may lead to instability in the electric bike, or even complete failure.
3. Overheating
- Symptoms: The controller surface becomes hot and may emit a strange smell.
- Causes: Continuous high load, poor heat dissipation, or high ambient temperatures can cause this issue.
- Impact: Overheating can affect performance and potentially cause permanent damage.
4. Incorrect Speed Display
- Symptoms: The speedometer displays inaccurate speed information.
- Causes: This may be due to a connection issue between the speed sensor and the controller or a software fault within the controller.
- Impact: Incorrect speed readings can increase the risk of accidents for the rider.
How to Repair the Controller
Tools Needed:
- Screwdrivers (both Phillips and flathead)
- Multimeter (to measure voltage and current)
- Cable cutters
- Electrical tape
- Disassembly tools (like a pry tool, if necessary)
Here are some basic repair steps to help you diagnose the problem and fix it:
-
Check Connections Ensure all connections between the battery and the controller are secure. Check each cable plug for looseness or corrosion. Always disconnect the power before inspection to avoid electric shock.
-

Detect Fault Codes If the controller has a fault indication feature, refer to the user manual for the fault code list and observe the flashing patterns of the indicator light to identify the specific problem.
-
Replace Components If you find that certain components inside the controller are damaged, they need to be replaced. Refer to instructional videos for guidance on replacing the controller, ensuring you use original parts for compatibility.
How to Maintain the Controller and Prevent Future Issues
Regular maintenance of your electric bike's controller is essential for optimal performance. Here are some key tips:
-
Keep Connections Clean
Regularly inspect and clean the connectors between the battery, controller, and motor. Ensure all connections are secure to avoid intermittent issues. -
Avoid Overloading
Be mindful of weight limits to prevent straining the controller and causing overheating. -
Ensure Proper Cooling
Allow for adequate ventilation around the controller. Avoid blocking air vents and let the controller cool down if it overheats. -
Check for Software Updates
Regularly look for firmware updates from the manufacturer to fix bugs and enhance performance. -
Conduct Routine Inspections
Periodically check for signs of wear, such as frayed wires or loose connections, and address any issues promptly. -
Store Properly
Keep your electric bike in a dry, temperature-controlled environment to protect the controller from extreme conditions.
