What is pedal assist?

The pedal assist system, also known as PAS, is a feature in e-bikes that provides electric assistance to the rider’s pedaling efforts. It enhances the overall riding experience by making it easier to pedal and maintain consistent speeds, especially when climbing hills or facing headwinds.

Especially when you love relying on that extra boost, just like me. Pedal assist is such a very important feature. 

How does Pedal Assist system work?

When you start pedaling, sensor detects your movement and sends a signal to the motor which provides you with appropriate power. This makes riding more easy and convenient.

There are different levels of pedal assist. You can adjust the amount of assistance you want from the motor based on your preference or the terrain you’re riding on.

Why is my Pedal Assist not working on my ebike?

There are some common reasons due to which pedal assist PAS sensor might not work. below we have figured out some common reasons and their troubleshooting guide.

1. Sensor Malfunction

In 70 percent of cases, this is the common problem. When the PAS sensor is misaligned or damaged, it fails to sense your pedal movement. So the motor does not engage.

To troubleshoot this issue, make sure that the sensor is aligned properly with the magnet on the crank. Also, clean it so that it can function properly. If you found PAS damaged or malfunctioning, kindly replace it.

2. Electrical Wiring Connections

Loose or damaged wires can interrupt the connection between the PAS sensor and the motor controller, causing the pedal assist to stop working. If you found any visible damage or loose connections, you can replace them or get them repaired. 

3. Battery Problems

This is also one of the common issues. If your battery is low on charge, it might not provide enough power to engage the motor. This can lead to the pedal assist failing to work. Always ensure your battery is fully charged and in good condition. If you suspect a battery issue, consider replacement.

4. Software Glitches in Controller

Sometimes, the issue might be related to the bike’s onboard software. A software glitch can disrupt the communication between the PAS sensor and controller, causing the pedal assist to malfunction. Checking for firmware updates or performing a system reset can often resolve these issues.

5. Motor Controller Issues

When the PAS sensor gives a signal to the motor, it provides appropriate power. However, if there is any serious mechanical issue in motor. Then it might not generate the necessary torque for you. In such cases consider repairing or replacing the motor with a professional technician.

How to Troubleshoot and Fix Pedal Assist Issues

When your pedal assist isn’t working, troubleshooting can often pinpoint the problem and lead to a quick fix. Here’s a step-by-step guide to help you diagnose and resolve the issue:
