Speed Sensors vs Torque Sensors: E-bike Sensor Technology

Speed Sensors vs. Torque Sensors E-bike Sensor Technology

Ebike manufacturers are building machines that make work easier and faster in this technological age. They invented the pedal-assist feature that makes users ride without using a throttle. However, this pedal-assist feature can best work using either the speed sensor or the torque sensor. The Haidong manufacturing company built its speed sensor at the bottom region of the bike.

The primary function of the speed sensor and torque sensor is to measure the level of the rotational speed ongoing in an e-bike. However, these sensors have distinct differences, further discussed in this article. If you are stuck between making the right choice of sensor for you, this guide might provide some help.

What is a Pedal-Assist?

A pedal-assist e-bike is an innovative product that involves converting stored batteries to an e-bike pedal system. As you ride, you will notice some extra push from your bike. However, pedal-assist does not mean a user will not need to pedal at all, but it makes riding much more effortless. It would help if you pushed the pedal button before operating your motor. Afterward, the level of support will be based on your bike setting.

Benefits of a Pedal-Assist E-bike

There are several reasons electric bikes are growing in popularity, with pedal-assist function topping the list. Hence, below are several reasons you should consider getting a pedal-assist e-bike.

Customizing your Riding Experience

A pedal-assist e-bike is essential if you want to customize your riding speed. It is more convenient to ride a pedal-assist e-bike, covering a long distance in a shorter timeframe. Meanwhile, speed and torque sensors are great contributors to this riding effect.

It is a Fast Alternative for Cyclists

You will enjoy a maximum riding experience with your e-bike, but you need to choose between a speed sensor or a torque sensor. Although countries like the United States have limited speed at which a user can ride, you can set a limit for yourself using the speed sensor. Also, it alerts you whenever you ride beyond the specified limit. This helps users ride faster with an e-bike than a traditional bicycle, especially since setting up your preferred speed limit.

Increases the Chances of People Riding E-bike

The presence of pedal-assist bikes increases the chances of people commuting with electric bikes. Also, the sensors make it easy for people to control their rides, removing the limitations for older adults and children. For instance, older people solve the challenges of climbing big hills by receiving extra support. Meanwhile, the sensors help them to adjust their ride appropriately.

Speed Sensors vs Torque Sensors: E-bike Sensor Technology

What are Speed Sensors?

A speed sensor is an essential feature of your bike because it notifies the rider of the speed you are running on. The speed sensor is relatively small in size, and it is built with a magnetic steel ring and induction contact. The magnetic steel is made at the crank area, passing information about the speed measures to the control device.

How Do Speed Sensors Work?

Most basic e-bikes designed for amateur riders are built with a speed sensor mechanism. It is safe to compare the working mechanism to how an electrical switch operates. With the magnet attached to the speed sensor, your e-bike motor is automatically ignited when it kicks off, while it stops after the operation. You get to control the pedal-assist and switch level through the speed sensor. This should be done manually, requiring some basic knowledge of speed limits and your state regulations.

A speed sensor is pretty flexible, with the pedal-assist responding based on the set level. However, when this assisted mode is set high, you may need to adjust the shift gears for more comfort. Although a speed sensor is more popular than a torque sensor, the latter has a significant advantage over it. The speed sensor pedal-assist mode is sometimes counterintuitive and jerky. Hence, you cannot rely on the power support you get from a speed sensor and respond to situations appropriately. For instance, the speed sensor provides unnecessary power going downhill, especially if your energy contribution is low.

What are Torque Sensors?

The torque sensors help to identify the amount of power that is being exerted on the pedaling activity. This torque sensor does not require much physical input from a rider. It allows you to enjoy a free ride as much as possible without slacking off. However, an e-bike is expected to have an increased assist level while riding uphill than downhill.

How Do Torque Sensors Work?

A torque sensor uses a strain gauge to measure the force exerted by the pedal-assist feature. It also measures the amount of pressure a rider executes to determine the bike’s electrical power—the power received by the motor increases as a user pedals harder, and vice versa. A torque sensor e-bike spins you higher and makes you feel heightened than the average riding speed. However, it is more common in higher ends e-bikes.

The torque sensor performs a more dynamic function than the speed sensor by analyzing users’ effort or input. For instance, you do not need to alter your motor power whenever you are climbing uphill manually. The sensor automatically signals the pedal’s need to provide extra assistance or control. The torque sensor provides a level of support that does not seem awkward as riding a regular bike. Manufacturers are building more sophisticated e-bikes that fit into the present societal needs. Hence, it is essential to choose your provider wisely while you greatly consider Haidong’s e-bike.

Differences Between Speed Sensors and Torque Sensors

Another name for the speed sensor is the cadence sensor, while the torque sensor is commonly known for its generic name. Going by the literal meaning, the speed sensor focuses on speed, while the torque sensor focuses on the generated torque level while riding. Also, a torque-sponsored e-bike is more expensive than a speed sensors e-bike. Hence, you may want to test-run the torque sensor before buying it to see if it is worth it.

The speed sensor has an easy mode of operation than the torque sensor. Users can simply regulate the pedal assistance expected from an e-bike using the inbuilt control button. However, this may make you feel like the motor is doing all the pedaling work. As a result, you may need to adjust the power level of the ride. On the other hand, the torque sensor allows you to exert some pressure while riding. This is a good option for riders who want to attain some level of exercise.

A speed and torque sensor successfully turns on a pedal-assist mode but at different timing and conditions. Whenever you ride below the specified speed, the speed sensor is responsible for activating the pedal mode. On the other hand, the torque sensor activates this mode when there is a need for extra force on the machine. It also records the level of power or forces an e-bike is getting.

The torque sensor improves the lifespan of an electric bike by enhancing the maximum range and battery level. The increased battery durability of the torque sensor is because the action does not engage the motor often. Also, the torque sensor executes more accuracy than the speed sensor in terms of precision. A torque sensor gives an accurate analysis of the force driving an e-bike so that a rider can make the necessary possible adjustment. However, a speed sensor also gives precision in its function but does not match torque sensor accuracy.

Conclusion

Both speed sensors and torque sensors are suitable, but each has advantages that make it a preferred option over another. It is essential to set out your needs and riding expectations. Nevertheless, the information provided above will help you to make clear decisions. You can also consult the Haidong manufacturing company for inquiries and recommendations on the most suitable option for you.
