Universal torque sensor for 2020, 2021, and 2022 Surface 604 eBikes. This sensor is the heart of the pedal-assist system, measuring the force you apply to the pedals and communicating that data to the controller in real time.
The result is electric assist that responds proportionally to your effort — pedal harder and you get more help, ease off and the motor backs down naturally. If your assist feels unresponsive, delayed, or inconsistent, the torque sensor is one of the first components to check.
