A transmission system ( 1 ), for instance of a bicycle, is described, comprising a drive wheel ( 2 ), a driven wheel ( 3 ), and a coupling chain ( 4 ) having a first chain half ( 4 C) and a second chain half ( 4 D). The transmission system is provided with a measuring device ( 6 ) for providing a measurement signal which is representative for the torque transmitted by the coupling chain ( 4 ). This measuring device ( 6 ) comprises a transverse force sensor arranged within the span of the coupling chain ( 4 ) in the form of a wheel ( 10 ) rotatably mounted on a supporting arm ( 20 ), which wheel touches the first chain half ( 4 C) and the second chain half ( 4 D). The measuring device provides a measurement signal which is a measure for the component (Fv), directed substantially perpendicular to the plane (L) defined by the rotation axes of the drive wheel ( 2 ) and the driven wheel ( 3 ), of the resultant (FDR) of the transverse forces (FDC, FDD) exerted to the sensing wheel ( 10 ) by the chain halves ( 4 C, 4 D).
