Understanding Pedal Assist System
Pedal assist is a popular feature in electric bikes (e-bikes) that provides assistance to the rider’s pedaling effort. It is also known as PAS (Pedal Assist System). The pedal assist system works by measuring the rider’s pedaling speed and force and providing a corresponding amount of power to the electric motor. This allows the rider to go further and faster with less effort.
There are different types of sensors used in pedal assist systems. The most common ones are cadence sensors and torque sensors. Cadence sensors measure the speed at which the rider is pedaling, while torque sensors measure the force applied to the pedals. Some e-bikes use a combination of both sensors to provide a more accurate and responsive pedal assist system.

How Pedal Assist Works
Pedal assist, also known as PAS (Pedal Assist System), is a feature found in many electric bikes (ebikes) that helps you to pedal with less effort. The system uses a sensor to detect the movement of your pedals and then activates the motor to provide additional power.
As you pedal, the PAS system continuously monitors your speed and adjusts the power assist accordingly.
When you start pedaling, the PAS sensor sends a signal to the motor, which then kicks in to provide extra assistance. The amount of power provided depends on the PAS level you have selected. Most ebikes have several PAS levels, which allow you to adjust the level of assistance to suit your needs.
As you pedal, the PAS system continuously monitors your speed and adjusts the power assist accordingly. This means that if you start pedaling faster, the system will provide more assistance, and if you slow down, it will provide less assistance.
It’s worth noting that the PAS system only provides assistance when you are pedaling. If you stop pedaling, the motor will stop providing power. This is an important safety feature that helps to prevent accidents and ensures that you remain in control of the bike at all times.
In summary, the PAS system is a great feature that makes cycling easier and more enjoyable. It provides additional power when you need it most and helps to reduce the effort required to pedal. With multiple modes and assist levels, you can customize the PAS level to suit your needs and preferences.
