There is disclosed a torque shaft (100) for connecting an input shaft (10) to an output shaft in a pedal assembly which is bound to the pedals of a pedal-assisted electric bicycle. The torque shaft comprises a first axial end portion (110) configured for being tightly fixed to the input shaft; a second axial end portion (130) configured for being tightly fixed to the output shaft; and a resiliently angularly deformable portion (120) extending axially between the first axial end portion (110) and the second axial end portion (130) for transferring torque from the former to the latter, namely from the input shaft to the output shaft. This elastic deformation portion has a given overall axial length and is shaped into a serpentine such that it has a developed deformational length that is longer than said overall axial length. Torque can thus be measured by magnetic flux increase due to angular deformation of the torque shaft, which is nevertheless adapted to the small axial dimensions of the pedal assembly of an e-bike.
