What was the starting point for the development of the sensor bottom bracket?
The market for bottom brackets has too many identical products, which made it difficult for us to stand out from other companies supplying this market. We succeeded in asking the right questions and finding out what the demands of tomorrow's customers will be in terms of mobility.

Please describe the main features of this innovation and its technical implementation:
The product's additional functions are a particularly innovative aspect. The sensor bottom bracket doesn't just support and guide the movements of the rider, it also monitors them and adjusts the output of the electric motor accordingly. And it does all of this without requiring any additional space.

The rider applies three physically measurable variables to the sensor bottom bracket: Torque, speed, and direction of rotation.

Speed and direction of rotation are recorded by a speed encoder. The torque measurement is at the heart of the sensor bottom bracket. This is done by magnetizing the corresponding section of the shaft. The magnetic field changes when the rider applies torque to the bottom bracket, and it is very easy to measure this change and thus determine the torque.

What customer benefits does this solution provide?
Both manufacturers and riders benefit from this solution: Manufacturers receive a compact unit that provides all of the data needed to perfectly regulate the pedelec, while riders always receive optimum support.

What does innovation mean for you personally?
For me personally, innovation means taking a proactive attitude to solving conflicting issues in development. This involves not blindly rushing into new tasks and then trying to find the answers, but first of all asking the right questions. Because only those who ask the right questions can overcome these obstacles and make real progress.
