A built-in motor for a bicycle and an electric powered bicycle, which relate to the technical field of the electric powered bicycle, and address the technical problems in the prior art of the complex structure and low measurement accuracy of torque sensors in built-in bicycle motors. The built-in motor for the bicycle comprises: a motor shell (011), a motor inner stator (012) fixed in the motor shell (011) by means of an inner stator frame; a motor outer rotor (013) installed on the inner stator frame, the motor outer rotor (013) and a motor body output shaft (014) being connected into a whole; a first planetary gear mechanism (015) arranged in the inner stator frame, the first planetary gear mechanism (015) being used for increasing input human force before outputting same; an outer gear ring of the first planetary gear mechanism (015) is connected with an elastic body (031), the elastic body (031) being fixedly arranged in the inner stator frame; a torque sensor (032) is arranged on the elastic body (031), the torque sensor (032) being used for measuring the pedaling force provided by a rider to the bicycle.
