A torque sensor assembly for a power-assisted bicycle (40) has a torque sensor (10), a one-way bearing (21), a chainwheel (22), two cranks (31) and two pedals (32). The torque sensor (10) has an envelope tube (11), a middle tube (12), a transmission axle (13), a resilient element (16, 16A) connected to the middle tube (12) and the transmission axle (13), a first disc and a second disc respectively attached to the transmission axle (13) and the middle tube (12), and a detection unit (19) detecting displacement angles of the second and first discs to calculate torques applied to the transmission axle (13) and to drive the power-assisted bicycle (40) according to the torque. The torque sensor assembly has a simple structure, fast, sensitive and accurate torque sensing ability, and can easily be assembled to all kinds of power-assisted bicycles.
