An electric balance bike comprising:
- a front wheel and a rear wheel;
- an electric drive source configured to rotationally drive at least one of the front wheel and the rear wheel;
- a first frame holding the front wheel and a second frame holding the rear wheel;
- a main frame connecting the first frame and the second frame and having a closed cross section;
- and
- an electrical device disposed to an inside of the closed cross section of the main frame in a state of being separated upward from an inner bottom surface of the closed cross section, the electrical device being configured to cause the drive source to generate power for which the drive source rotationally drives,
- wherein the electrical device includes a battery configured to supply electric power to the drive source,
