Sensoric bottom brackets by NCTE – Torque and speed sensing

For Electric bikes / Pedelecs

NCTE optimizes the performance of electric bikes (»pedelecs«). A torque sensor integrated into the bottom bracket or middle motor continuously measures:

Model RT – (speed, direction of rotation, and torque)
Model R – (speed and direction of rotation)

to determine the cyclist’s pedaling strength at any given moment. The motor’s drive power is then controlled accordingly.


Extra comfort and power for the cyclist, excellent driveability, extended range.

For applications, where standard bottom bracket sensors cannot be used, we deliver customized torque and rotation sensor solutions to your specification.

NCTE sensor solutions have already been integrated into a vast variety of electric drive systems. How can we help you?
