A pedal force detection mechanism for an electric-assisted bicycle includes a torque-transmitting member, a main thrust bearing, a strain sensing assembly, and a main drive gear. The torque-transmitting member transmits and diverts a torque along a crankshaft's axial direction. The main thrust bearing abuts against the torque-transmitting member to transmit the diverted torque. The strain sensing assembly has a strain gauge, resilient ring-shaped base, and supporting annular base. The supporting annular base abuts against a shaft housing. An axial-strain gap is defined between the supporting annular base and the main thrust bearing. The resilient ring-shaped base is fitted between the main thrust bearing and the supporting annular base. A main gear and an internally-connected ring body of the main drive gear are integrally formed with each other. An axial-movement gap is defined between the torque-transmitting member and the internally-connected ring body.
