Power Meets Efficiency: How Torque Sensors Optimize Electric Trike Performance

By Addmotor | 23 October 2023 | 0 Comments
In the ever-evolving world of electric mobility, the best electric trikes for adults have gained remarkable popularity. These three-wheeled wonders offer a perfect blend of convenience, stability, and fun.
And when we talk about what's transformed the etrike world, one technology that stands out is the torque sensor. With a torque sensor, the motor power of an etrike blends with efficiency and creates a cycling experience like you've never felt before.
If you are an etrike enthusiast seeking the best possible riding experience, it is worth knowing about torque sensors and how they work. In this article, we'll explore the differences between torque sensors and cadence sensors, and understand why torque sensors are the preferred choice for optimizing electric trike performance.

What is a Torque Sensor?

Before we delve into why torque sensors are pivotal in optimizing electric trike performance, let's understand what these sensors are. A torque sensor is a device that measures the force applied to the pedals while riding an electric trike. Then, it enables the trike to adapt the power assistance dynamically to the rider's effort. Simply put, as soon as you begin pedaling, the sensor detects your pedal power and instantly powers up the electric motor, giving you a smooth boost that complements  your own effort. When you're riding at a low pressure, the torque can give your pedaling an extra 50% boost. But if you apply more pressure, some e-trikes can crank that up to 300%.

Unlike traditional pedal-assist systems, which rely on cadence sensors, torque sensors provide a more accurate and natural riding experience, as the rider only has to pedal as hard as they need to.


The differences between a Torque Sensor and  a Cadence Sensor

Etrikes are generally designed with two types of sensors such as a cadence or a torque sensor.
To appreciate the significance of torque sensors, it's essential to understand the differences between them and cadence sensors.  
Cadence sensors, commonly found in older etrikes, measure the speed at which a rider pedals. It's more of like an on/off switch, that turns the motor on when you pedal and turns the motor off when you stop pedaling. This means that the electric assistance is based on how fast you pedal rather than how hard.
In contrast, torque sensors measure the actual force you apply to the pedals, offering a more intuitive riding experience. With a torque sensor, the electric trike can instantly detect when you're pedaling harder, such as when going uphill or accelerating. This immediate response creates a seamless and natural feeling of additional power without even requiring manual adjustments.

However, to get a quick understanding of the differences between these sensors, let’s check out the table below-
Categories Cadence Sensor Torque Sensor
Measurement Speed or rotation of the pedals Force or pressure applied to the pedals
Assistance Type Constant and fixed assistance based on speed Proportional and variable assistance based on effort
Riding Experience Tends to offer a more on/off feel Natural and intuitive riding experience by adjusting motor assistance in real-time.
Cost Cheaper Expensive
Impact on Efficiency May cause sudden accelerations and speed limitations Improves the efficiency and performance of the electric motor
Longevity and Maintenance With simpler mechanics it may offer an advantage in longevity With more advanced mechanics, it might demand more maintenance and care over time.

Why Torque Sensor is Better for Electric Trikes (Advantages)

Now that we have a clear understanding of torque sensors and their differences from cadence sensors, let's explore why torque sensors are the superior choice for best electric trikes for adults.

1. Precise Power Delivery

One of the standout advantages of torque sensors is their ability to provide precise power delivery. When you apply more force to the pedals, the motor responds accordingly. This precision not only optimizes your electric trike's performance but also conserves battery life by using power only when necessary.
The Addmotor’s TRIKETAN M-330F, for example, comes with 36 torque sensing points that can save battery power and also extend your riding range by around 20% to 30%. This is especially beneficial for adults using eTrikes for commuting or recreational rides.

2. Natural Riding Experience

Torque sensors create a riding experience that feels natural and responsive. As you apply more force to the pedals, the motor assists you accordingly. This responsiveness is particularly advantageous for etrike users, providing a seamless transition between pedaling and motor support. The Addmotor ARISETAN II M-360 2024, for instance, leverages this technology to deliver a smooth and enjoyable ride.

3. Climbing Hills with Ease

Best electric trikes for adults are equipped with torque sensors making conquering steep inclines a breeze. As you exert more effort while ascending a hill, the sensor detects this and provides extra power, making uphill rides much less daunting. The TRIKETAN II M-330 for adults showcases this capability, making it an ideal choice for riders in hilly areas.

4. Consistent Speed Control

Torque sensors ensure consistent speed control. They adapt to your pace, allowing you to effortlessly maintain your desired speed. Whether you're looking for a leisurely cruise or a quicker journey, torque sensors help you achieve it with precision.

5. Reduced Wear and Tear

Compared to cadence sensors, torque sensors reduce wear and tear on your eTrike's drivetrain. With power delivery synchronized to your pedal force, there is less strain on the components, resulting in longer-lasting and more reliable etrikes.


When it comes to etrikes for adults, both power and efficiency are necessary. This is where torque sensors have revolutionized the eTrike experience by providing precise power delivery, enhancing efficiency, and delivering a natural riding experience.
Therefore, when selecting the best electric trike for your needs, consider those equipped with torque sensors, like the Addmotor models mentioned above. With these technological advancements, eTrikes have truly become a powerhouse of innovation and enjoyment, offering a seamless blend of human effort and electric assistance.
So, ride on with confidence, knowing that the future of electric trikes has arrived, and it's powered by torque sensors.
