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.
