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 how to mount a camera on an e-bike for beginners. Now, let’s dive into a crucial topic: preventing your electric bike from overheating.

How to Avoid Controller Overheating

Overheating in the controller is not uncommon and may not be immediately dangerous. However, if the controller is located in a confined space with limited airflow, it can become a serious issue. Check where your controller is placed—does it have enough ventilation? Is it exposed to the air or tucked away somewhere?

Here are some solutions to prevent overheating:

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

Avoiding Motor Overheating

Electric bike motor overheating can lead to long-term damage. It’s essential to monitor the temperature while riding, especially when going uphill or over rough terrain like sand or gravel. While short bursts of high load are generally safe, prolonged stress can harm the motor.

Typically, a constant load for about 20 minutes can cause the motor to reach temperatures above 200°F. If you're an adventurous rider, remember to take breaks of 10–15 minutes after extended use to let the motor cool down. Also, avoid riding on flat tires, as this increases strain on the motor, especially on uneven surfaces.

Delfast Electric Bikes: Designed to Prevent Overheating

What do Delfast engineers recommend? The TOP 3.0 model features a ventilated frame that naturally cools as it moves. The controller is mounted externally with a radiator, which helps prevent overheating. As one of our engineers says, “With its advanced design, the Delfast E-bike is built to withstand tough conditions. In hot weather, simply park it in the shade, and it will last for years.”

Summary

To ensure your e-bike runs smoothly and lasts longer, follow these tips:

• Improve or replace the cooling system for your controller.
• Inspect and replace transistors in the controller if needed.
• Monitor the load on both the controller and motor.
• Keep an eye on motor temperature during rides.
• Avoid continuous high-speed riding for more than 20 minutes.
• Take regular breaks to let the motor cool down.
• Don’t ride on flat tires, especially on rough terrain.
