Transmission for electric bicycles for detecting a torque and related method for electric bicycles for detecting a torque

A transmission for an electric bicycle for detecting an applied torque that acts upon a pedal crank shaft arrangement, comprising:

• a pedal crank shaft, upon which the applied torque acts;
• an output shaft configured for connection to an output;
• a sensor shaft offset in parallel with the pedal crank shaft;
• and
• a force sensor connected to the sensor shaft, which detects a force exerted by the sensor shaft which corresponds to the torque to be detected;
• a drive-side sensor transmission;
• and
• an output-side sensor transmission;
• wherein the drive-side sensor transmission connects the pedal crank shaft to the sensor shaft and the output-side sensor transmission connecting the sensor shaft to the output shaft, wherein the drive-side sensor transmission transmits the applied torque from the pedal crank shaft to the sensor shaft, and wherein the output-side sensor transmission transmits a torque corresponding to the applied torque from sensor shaft to the output shaft, and wherein the drive-side sensor transmission has a gear ratio which differs from the gear ratio of the output-side sensor transmission.
