Zusammenfassung:	To provide a bicycle drive unit capable of improving a maintenance work easiness.SOLUTION: A drive unit 10 includes: a first power system that includes an electric motor 30; and a second power system that includes a crank shaft 61 to which pedals are attached. The second power system transmits the rotation of the crank shaft 61 to a rear wheel hub 41 via a second transmission shaft 27 and a first transmission shaft 21. A rear arm 50 and the second transmission shaft 27 are placed at the left side relative to a rear wheel 40. The first transmission shaft 21 is placed inwardly relative to a stator 31, and is coupled to the rear wheel hub 41 at the opposite side to the second transmission shaft 27.SELECTED DRAWING: Figure 6 【課題】メンテナンス作業性を向上できる自転車の駆動ユニットを提供する。【解決手段】駆動ユニット１０は、電動モータ３０を有している第１動力系と、ペダルが取り付けられているクランク軸６１を有している第２動力系とを有している。第２動力系は、クランク軸６１の回転を、第２伝達軸２７と、第１伝達軸２１とを介して後輪ハブ４１に伝える。リアアーム５０と第２伝達軸２７は、後輪４０に対して左方に配置されている。第１伝達軸２１はステータ３１の内側に配置され、第２伝達軸２７とは反対側で後輪ハブ４１に連結されている。【選択図】図６
