Application 

The bottom bracket sensors are used in all types of e-bikes. From city- to trekking- and cargo bikes. They 
provide the necessary signals for a harmonious and individual riding experience with battery-saving motor 
support. S-pedelecs can also be equipped with these sensors. 

General 

Please read this data sheet including the assembly instructions (at the end of this document) carefully before 
first use and only use the product accordingly. Keep this for future reference to avoid any misuse. For correct 
installation, please proceed according to the installation instructions. For more information, please contact 
our customer service at [email protected]

Explanation and operating instructions refer only to the sensor in the condition in which it was placed on the 
market. Parts subsequently attached by the end user and/or interventions subsequently made are not taken 
into account. 

Manufacturer 

The manufacturer of the S-BB-R, S-BB-RP and S-BB-RT series sensors is: 
 
NCTE AG 
Raiffeisenallee 3 
82041 Oberhaching

Phone: + 49 (0) 89 665 619-0 

Intended use and installation range

 

The sensor is intended for use in bicycles with electric drive (pedelec, e-bike and electric bicycle) within the 
meaning of Section 39 (7) of the German toad traffic regulations. Use the product only in bicycle frames with 
a BSA threaded bottom bracket and a frame width of 68 mm or 73 mm. Crank arms must be mounted on the 
square shaft ends. The sensor S-BB-RT measures the torque applied by pedal and crankshaft at the left crank. 
All  sensors  record  speed  and  direction  of  rotation.  For  safety  reasons,  the  motor  support  may  only  be 
activated if both speed outputs provide several correct and plausible signal sequences. 

For this purpose, the direction of rotation and the speed must be determined from both signals and checked 
for sensible limit values. 

Any  other  use  is  considered  improper  and  may  result  in  property  damage  or  even  personal  injury.  The 
manufacturer accepts no liability for damage resulting from improper or incorrect use.
