NCTE S-BB-R Torque Sensor – 10,000 Nm | E-Bikes | Bottom Bracket Bottom Bracket

NCTE S-BB-R Torque Sensor for E-Bikes and Pedelecs | Maximum Precision

Manufacturer: NCTE Torque Sensors
Category: Very high torque (10,000-150,000 Nm), Rotary, Torque sensor

The NCTE S-BB-R sensor represents NCTE's specialized solution for torque measurement in electric bicycle drive systems. Installed on the bottom bracket without axle modification, it provides continuous measurement of pedal torque and rotation direction using a 16-pole magnetic sensor (CPR).

Certified under ISO 4210:2014 (Bicycle Safety), it offers robust environmental protection with IP66 external and IP63 internal encapsulation, allowing reliable operation in adverse weather conditions (rain, dust, humidity). The signal output is customizable according to the electric bicycle controller interface, with a 250 Hz sampling rate for real-time response.

Ideal for OEM manufacturers of electric bicycles, PAS (Pedal Assist Systems), sustainable e-mobility research laboratories, and validation of human-assisted propulsion systems. Available in compatibility with major Thun X-Cell RT, X-Cell R, and FAG bottom bracket variants, ensuring direct integration without complex modifications.

Frequently Asked Questions

Is it compatible with all bicycle bottom brackets?

No, it's optimized for Thun X-Cell RT, X-Cell R, and FAG bottom brackets. Check specific compatibility before purchasing.

What is ISO 4210:2014?

It is the international standard for bicycle safety. The NCTE S-BB-R certification guarantees compliance with electronic bicycle safety specifications.

How does rotation direction measurement work?

The 16-pole magnetic sensor allows simultaneous detection of angular velocity (RPM) and pedaling direction through magnetic pulse analysis.
