It is preferable that the motor 42 of both the embodiments shown in FIGS. 4 and 6 has its rotor rotation shaft arranged perpendicularly to the crankshaft 36, as in the embodiment shown in FIG. By doing so, it becomes possible to reduce the width near the bottom placket 16. In addition, in the embodiments shown in FIGS. 1 and 4, the controller 50 and battery 52 are arranged almost parallel to the rotor rotation axis of the motor 42, so they are not wasted along the seat tube 18 and down tube 20, which are frame members. Can be stored compactly without creating any voids. Furthermore, in these embodiments, since the controller 50 is disposed between the motor 42 and the battery 52, the electrical wiring can be sufficiently short.

[Effects of the Invention] As described above, the present invention provides electric motors, batteries, etc. along the frame member extending from the bottom bracket.
Since the controller is installed and the electric motor is connected to the bottom bracket, the electrical wiring cord that connects them becomes very short. Furthermore, since these are adjacent to each other, even if they are covered with a cover, one common cover is sufficient, and this cover can be made smaller. Therefore, when attaching a cover, there is no need to divide the cover into many parts, the number of parts is reduced, and the size of the cover can be made smaller.
