A torque measuring device for an electromotive chainless bicycle is provided. The bicycle comprises a power transfer shaft between the crank assembly and a passive gear of a hub of a rear wheel, a motor for providing auxiliary power, and a torque measuring device for measuring output torque of the motor. The torque measuring device is installed on the power transfer shaft which is a rearmost section of power transfer of the bicycle so as to measure and control the output torque of the motor. The power transfer shaft is divided into two parts; a front part is a power output unit, which can output a torque from the crank; and a rear part is a transfer unit for transfer torque to a rear wheel for driving the rear wheel; and the torque measuring device is arranged between the power output unit and the transfer unit.
