Whether you're a seasoned e-bike rider or just starting out, it's important to understand how to maintain your electric bike properly. In our previous article, we covered the best ways to mount a camera on your e-bike for beginners.

Preventing Controller Overheating

Controller overheating is a common issue that can occur, but it’s not always dangerous in the short term. The location of the controller plays a big role in how quickly it heats up. Is it placed in a well-ventilated area, or is it enclosed and hidden? Checking the placement is a good first step.

Here are some solutions to prevent overheating:

• Upgrade to a more powerful controller if needed.
• Disassemble the controller and check the transistors — replace them if necessary.
• Install or improve the cooling system for better heat dissipation.

Avoiding Motor Overheating

Monitoring your motor temperature is essential because motor overheating can lead to serious damage over time. Riding on rough terrain like sand or gravel, or climbing steep hills, increases the load on the motor.

While occasional high loads aren’t harmful, prolonged use can cause overheating. A motor typically reaches critical temperatures (over 200°F) after about 20 minutes of continuous use. If you’re an avid rider, take regular breaks—10 to 15 minutes—to let the motor cool down.

Also, be mindful of tire pressure. Riding with underinflated tires adds extra strain on the motor, especially on uneven surfaces. Make sure your tires are properly inflated before heading out.

Summary: Key Tips to Prevent Overheating

To keep your e-bike running smoothly and avoid overheating, follow these tips:

• Improve or install a cooling system for your controller.
• Check and replace any faulty transistors in the controller.
• Monitor the load on both the controller and motor.
• Keep an eye on the motor temperature.
