When shopping for an electric bike, you’ll often see terms like torque sensor and cadence sensor listed in the specifications. These two types of pedal-assist sensors play a major role in how your e-bike feels to ride. But what exactly is the difference, and which one should you choose? Let’s break it down.
What Is a Cadence Sensor?
A cadence sensor is the most common type of pedal-assist system in e-bikes. It works by detecting whether or not you are pedaling and then sending a signal to the motor to provide assistance.
-
How it works: It uses magnets and a sensor near the crank to measure pedal rotations.
-
Riding feel: The motor kicks in as soon as you start pedaling, regardless of how hard you pedal.
-
Advantages:
-
More affordable than torque sensors.
-
Simple and reliable technology.
-
Good for riders who prefer steady motor support with less effort.
-
-
Disadvantages:
-
Can feel less natural because assistance is not based on pedal pressure.
-
May cause a slight delay when starting or stopping.
-
What Is a Torque Sensor?
A torque sensor is a more advanced pedal-assist system that measures how hard you are pedaling and adjusts the motor power accordingly.
-
How it works: It detects the pressure you apply on the pedals and sends proportional power to the motor.
-
Riding feel: The harder you pedal, the more assistance you get—creating a natural and responsive cycling experience.
-
Advantages:
-
Smooth, intuitive, and natural ride feel.
-
Extends battery life because the motor only provides the needed assistance.
-
Great for hilly terrain or riders who enjoy a workout.
-
-
Disadvantages:
-
Typically more expensive than cadence sensors.
-
Requires more advanced technology and maintenance.

Key Differences Between Torque and Cadence Sensors
| Feature | Cadence Sensor | Torque Sensor |
|---|---|---|
| Measurement | Pedal rotations (speed of pedaling) | Pedal pressure (force applied) |
| Ride Feel | Less natural, motor engages when pedaling | Smooth, natural, responsive assistance |
| Battery Efficiency | Less efficient, motor runs more frequently | More efficient, only adds power as needed |
| Cost | More affordable | More expensive |
| Best For | Casual riders, commuters on flat roads | Riders who want a realistic cycling feel, hills, and longer rides |
Which One Should You Choose?
-
Choose a cadence sensor if you’re looking for a budget-friendly e-bike, you mainly ride on flat terrain, and you want consistent assistance without worrying about how hard you pedal.
-
Choose a torque sensor if you want a natural, responsive ride, better battery efficiency, and plan to ride on varied or hilly terrain. Among EBYCCO's bicycles, the C8 and C9 use cadence sensors.
Final Thoughts
The choice between a torque sensor and a cadence sensor comes down to your riding style and budget. If you’re after a smooth, intuitive cycling experience and don’t mind spending a little more, go for an e-bike with a torque sensor. If you prefer simplicity and affordability, a cadence sensor may be all you need.
By understanding the differences, you can choose the right electric bike that matches your lifestyle—whether that’s commuting through the city or exploring challenging trails.
