A power transmission unit for electric bicycles includes an input structure, an output structure, a torque detection unit, a detection target, and a detection unit. The input structure includes an input shaft. The input shaft is caused to rotate by external force transmitted thereto. The input structure rotates along with the input shaft. The output structure outputs rotational power by rotating along with the input structure. The torque detection unit is provided on an outer periphery of the input structure. The detection target rotates either along with, or while interlocking with, the input structure. The detection unit detects a rotational state of the detection target. At least part of the torque detection unit and at least part of the detection target overlap with each other when viewed perpendicularly to a rotational axis of the input structure.
