The invention relates to a torque sensor device and a power-assisted bicycle. The torque sensor device comprises a five-way assembly; the first bearing is arranged in the five-way assembly, the middle shaft is arranged in an inner ring of the first bearing in a penetrating mode, and the middle shaft can rotate around a rotating axis relative to the five-way assembly through the first bearing; the pressure sensor is arranged between the outer ring of the first bearing and the five-way assembly in the radial direction of the middle shaft, and the middle shaft can transmit acting force to the pressure sensor through the first bearing; or, the five-way assembly comprises at least two parts in the radial direction of the middle shaft, the pressure sensor is arranged between the two parts of the five-way assembly in the radial direction, and the middle shaft can transmit acting force to the pressure sensor through the first bearing and the parts. The torque sensor device can be connected with the main control circuit in a wired mode, so that the structure is simple, and the production cost is reduced.
