Integrated angle sensor for detecting speed and direction 
of rotation 

 

Suitable for frames with BSA 68 and BSA 73 (other 
options on request) 

 

Compliant with DIN EN 15194:2018-11 for city and 
trekking bike applications 

 

 

The  bottom  bracket  sensors  S-BB-R,  S-BB-RP  and  S-BB-RT  are  bottom  brackets  with  integrated  sensor 
technology. The sensors are our long-standing and successful solution for detecting speed and direction of 
rotation. The S-BB-RT sensor can additionally measure the torque on the crankshaft. 

The measuring principle for torque measurement is based on magnetostriction and is completely  without 
contact. The robust design of all sensor types is specially developed for demanding use in e-bikes. Our many 
years of experience show that our sensors are up to any requirements and do not need to be recalibrated 
even after years of use. Our sensors have also proven their performance and  durability in the laboratory. 
They meet the requirements of DIN EN 15194:2018-11 for the city and trekking sector, as well as the 96-hour 
salt-water spray test according to DIN EN 60068-2-252:2018. 

Our torque sensor ensures that your e-bike rides the way your customers expect it to: dynamic, harmonious 
and easy on the battery. 

We are happy to supply our sensors for your small, medium and large series. Corresponding samples are 
shortly available at any time. 

Your benefits at a glance: 

 

Completely non-contact measuring system 

 

No recalibration necessary  

 

Easy and intuitive mounting 

 

Made in Germany
