How the Electric Motor Works

The electric motor powers the bike by providing additional propulsion. In a pedal assist electric bike, the motor is typically located near the bottom bracket, which is where the pedal cranks are attached.

When the rider starts pedaling, the motor is activated and provides assistance based on the level of pedal pressure applied. The electric motor mechanics involve a power transmission mechanism that converts the electrical energy from the battery into mechanical energy to drive the bike forward. This mechanism usually consists of gears and a chain that connects the motor to the bike’s drivetrain.

As the rider pedals, the power from the motor is transmitted through the drivetrain, propelling the bike forward. The role of the pedal sensor in this process will be discussed in the subsequent section.

The Role of the Pedal Sensor

To understand how the pedal sensor functions, you need to know how it detects your pedaling motion and communicates with the electric motor. The pedal sensor is a crucial component of a pedal assist electric bike as it determines when and how much assistance to provide.

It works by utilizing a variety of sensors, such as hall effect sensors or torque sensors, to detect the rotation of the pedals. This information is then sent to the electric motor, which calculates the appropriate amount of power to deliver. However, it is important to note that the pedal sensor may require calibration to ensure accurate readings.

Troubleshooting pedal sensor issues may involve checking the wiring connections, adjusting the sensor position, or replacing faulty components. With a properly functioning pedal sensor, the electric motor can seamlessly provide assistance based on your pedaling input.
