❓ Frequently Asked Questions
Is this torque sensor compatible with all Bafang motors?
No. This sensor is compatible only with Bafang hub systems that support torque sensing. Please check your motor and controller specifications before ordering.
Is this part compatible with EconicOne e-bikes?
Yes, this torque sensor is compatible with selected EconicOne electric bicycle models (CrossCountry, Urban, Comfort Limited) that use Bafang torque-based systems. If unsure, contact us with your bike model.
What is the difference between a torque sensor and a cadence sensor?
A torque sensor measures how hard you pedal and adjusts motor power accordingly, providing a smooth and natural riding experience. A cadence sensor only detects pedal rotation and delivers more basic assistance.
Do I need professional installation?
Yes, professional installation is strongly recommended. Specialized bottom bracket tools are required, and incorrect installation may damage the sensor or affect system performance.
Does this part improve battery efficiency?
Yes. Because motor assistance matches rider effort more precisely, torque sensing systems typically use battery power more efficiently than cadence-only systems.
