Many people in Europe opt for e-bikes as they are cheaper, more eco-friendly, and offer faster commutes. These electric bikes have various components to ensure the proper functioning of the vehicle and a safe and comfortable riding experience. One of these components is the electric bike sensor, which is an important component to make your riding safer and easier.

Next, let's follow this guide to learn about the various types of ebike sensors.

What is an EBike Sensor?

An e-bike sensor is a device integrated into an electric bicycle to monitor various aspects of the bicycle's performance, guiding the motor to on when and how a rider needs assistance, and plays a vital role in enhancing the functionality, safety, and efficiency of e-bikes.

Where are E-Bike Sensors Located?

The position of an electric bike sensor depends on the type, so you will find e-bike sensors in different locations of the e-bike. Some common sensor locations include:

  • Pedal Assist Sensor: The ebike pedal sensor is mounted on the bottom bracket, between the pedals and cranks.
  • Torque Sensor: You will see it on the bottom bracket or the crankset.
  • Brake Sensor: It is mounted near the brake lever or inside the brake caliper.
  • Speed Sensor: An ebike speed sensor is usually located on the spokes or the brake disc mount.
  • Cadence Sensor: It is located on the crank of the bike.

Types of Ebike Sensors

Ebike sensors come in different types and have different functions. Let's take a look!

1. Pedal Assist Sensor (PAS Sensor)

The e bike pedal sensor detects your pedalling activity, i.e. the rotation of the pedals, to determine your pedaling speed and signals the motor for power assistance. It allows you to concentrate on pedalling without having to manually control the motor.

2. Torque Sensor

Also known as a force sensor, the torque sensor responds to the pedaling cadence while measuring the force you use to pedal. It helps the motor provide proportional assistance based on how hard the rider pedals, making for a more natural and responsive ride. For example, when you pedal faster, the motor reduces its power.

3. Speed Sensor

The ebike speed sensor measures the speed of the bike. When the e-bike reaches the set speed, such as 25 km/h, it switches off the motor. Some specialized speed sensors direct the motor to gradually reduce the speed before the ebike reaches the maximum speed.

4. Cadence Sensor

A cadence sensor or motion sensor tracks the rotational speed of the pedals, reacting to the cranks of the pedals. It will send signals to start the motor when the ebike crank moves forward, and stop the motor when the rider stops pedalling.

An e-bike with a cadence sensor requires minimal effort from a rider to start moving, so it is ideal for older people or those with health issues. However, there may be a delay in its start-up because when you start the e-bike, it may take a few seconds to send the signal to the motor.

5. Brake Sensors

The brake sensors detect when you apply brakes and send a signal to the ebikes motor controller to cut off power. The ebike will then slow down or stop, preventing further propulsion. Brake sensors are of use when you ride in traffic or steep descents.

When the brake sensors cut off the power, they prevent unnecessary strain on the motor and help to conserve the ebike's battery.

6. Throttle Sensor

A throttle sensor monitors your throttle input while controlling the motors motor input. It offers an alternative mode of assistance that allows you to control the motor's power output without pedaling. This is often used in conjunction with other sensors to provide a more balanced riding experience.

There are three types of throttle sensors:

  • Finger throttle: It's a small lever that you can press or pull with your fingers.
  • Thumb throttle: You can push down the lever with your thumb to control the power.
  • Twist throttle: You'll have to twist a grip on the handlebar to control the ebike's power.

7. Battery Level Sensor

By monitoring the charge level of your e-bike, you can receive real-time information about the remaining power, adjust your riding style, and take advantage of the remaining battery charge. The battery level sensors ensure that you can plan your journey better and reduce the risk of your e-bike running out of power.

8. Temperature Sensor

E-bike temperature sensors detect changes in component temperature, helping you diagnose potential issues, especially with the battery. Such sensors ensure that your e-bike battery operates at an ideal temperature, extending the battery life and maintaining its efficiency.

9. Gyroscopes and Accelerometers Sensors

Both sensors measure your ebike acceleration, offering more controlled stability. Some, like the Bosch ebike sensor, can unlock advanced riding features.

10. PS and Navigation Sensors

GPS (Global Positioning System) is able to track the location of an e-bike and provide a record of its route, even updating with real-time traffic, ensuring a smooth ride. When a navigation sensor works alongside GPS, it can provide additional data such as speed, altitude, and direction. Some navigation sensors allow you to download maps in advance in case there is no active internet connection, making it easier for you to explore and commute.

11. Pressure Sensors

Pressure sensors monitor tyre pressure, ensuring your ebike maintains an adequate grip on the road. You'll be able to sort any deviations by using the pressure sensor' real-time data.

Pressure sensors also monitor the suspension systems, which compress and absorb the impact on uneven terrains while cushioning you.

12. Optical and Light Sensors

Optical and light sensors help you adjust the light by detecting the brightness of the outside light, enhancing your visibility, especially in poor conditions. Specific e-bikes have more advanced light sensors that allow for adaptive lighting, dynamically adjusting brightness and beam patterns to optimize visibility without inconveniencing other road users.

13. Proximity Sensors

Proximity sensors detect objects along your path, providing you with timely warnings. The sensors trigger speed reduction or automatic braking once they sense any objects ahead. The use of such sensors ensures you ride comfortably in busy urban areas.

Conclusion

Proper use of ebike sensors can improve the performance and safety of the vehicle while making you feel more comfortable. Therefore, when choosing an e-bike, you can pay attention to the sensors used in the vehicle to confirm whether it matches your needs.
