Yamaha E-bike Speed Sensor

The speed sensor on a Yamaha e-bike is an essential component that measures the bike's speed and ensures the motor assists properly. It consists of two parts: the speed sensor and the magnet, which together track the movement of the bike. Proper installation and functioning of the speed sensor are crucial for the e-bike's performance and safety.

Parts of the Speed Sensor:

Speed Sensor: Typically installed on the rear fork and connected to the motor's control unit.

Magnet: Attached to the rear wheel's spoke or rim, passing by the sensor with each wheel rotation.

General Information on the Speed Sensor:

• Compatibility: Yamaha provides speed sensors compatible with all their systems. For example, a 650 mm long speed sensor is available for various models.
• Installation: It is important to ensure that the magnet and sensor are at the correct distance from each other for the system to work properly.
• Maintenance: Regular checks and cleaning ensure the sensor and magnet function flawlessly.

If the speed sensor is not working properly, it can affect motor assistance and the speedometer readings. In such cases, it is recommended to check the position of the sensor and magnet as well as any potential damage. If necessary, it is advisable to contact an authorized Yamaha service center.
