PROBLEM TO BE SOLVED: To provide a support structure of a bicycle electric motor, which can suppress the axial movement of an output shaft, and a bicycle drive unit including the same.SOLUTION: A support structure is for a bicycle electric motor that comprises a rotor, a stator and an output shaft rotated with the rotor. The support structure includes a support part, a first inner ring body, a first outer ring body, and first rolling bodies provided between the first inner ring body and the first outer ring body. One of the first inner ring body and the first outer ring body supports a portion of the output shaft between a first portion thereof connected to the rotor and a second portion thereof connectable to another member. The other of the first inner ring body and the first outer ring body includes a first bearing supported by the support part, and a first regulation member that is formed separately from the support part, is arranged coaxially with the output shaft and regulates a movement of the other of the first inner ring body and the first outer ring body in a first direction directed from the first portion toward the second portion along the shaft center of the output shaft.SELECTED DRAWING: Figure 5
