Torque Sensor vs. Cadence Sensor on EBike: Which One Is Best?

The sensor of an eBike is another way to provide assistance besides the throttle. It can provide you with different degrees of assistance during riding and improve your riding experience. There are two types of pedal assist sensors on the market: torque sensors and cadence sensors. The torque sensor adjusts the motor power according to your pedaling force to provide you with assistance, while the cadence is based on your pedaling speed.
I will compare the differences between them and help you choose your best solution.

What is a torque sensor?

The torque sensor adjusts the motor's power proportionally to the rider's pedaling force. It can respond to the rider's force, bringing a more natural and smoother riding experience. This means that if you pedal harder, the motor will output more power and the speed will be faster, and vice versa. It is similar to a traditional bike, but it will provide you with extra power. This will be a good choice for people who want to exercise and stay healthy.
Generally speaking, higher-end ebikes will choose torque sensors as their standard configuration.

What is a cadence sensor?

Unlike torque, a cadence sensor measures the rider's pedaling rotation (speed rather than force) and provides assistance based on your preset power level. This means that if you want to ride at high speed, you need to increase your pedaling speed. But at very high speeds, pedaling may no longer have any effect on the bike's motor output power and speed. This is what people often call a "ghost pedal".
This sensor is commonly found in economy and mid-range electric bikes, and is relatively cost-effective.

Key Differences Between Cadence and Torque Sensors

Which Sensor is Right for You?

Choose a torque sensor:

For those who like a more natural riding experience, pursue riding performance (climbing, long-distance riding), want to exercise and keep healthy during riding, and prioritize efficiency and smooth power output, we recommend that you choose an ebike with a torque sensor.

Choose a cadence sensor:

If you like simple, continuous pedal assistance, or you have a limited budget and want to choose an affordable one, then an ebike with a cadence sensor is also a good choice. It is suitable for riding casually for commuting or leisure.

Can You Upgrade from Cadence to Torque Sensor?

For those who have already bought a bike with a cadence sensor, they will wonder if they can upgrade to a torque Sensor. But this is usually difficult because the system is integrated, and the controller and other electronic components are already preset.
Therefore, it is best to buy an e-bike with the preferred sensor from the start.

Conclusion

Choosing between an ebike cadence sensor and a torque sensor ultimately depends on your riding style, budget, and performance preferences.  

If you prioritize cost and ease of use, a cadence sensor may be the right choice. But if you want precision, efficiency, and a premium riding experience, a torque sensor is worth the investment.
