Abstract
An electric two-wheel vehicle includes a battery case that accommodates two batteries. The battery case is open in an upward direction. A head pipe supports a steering shaft and is connected to a front portion of the battery case. The battery case includes a beam portion that is disposed between the two batteries and extends rearward from a front wall portion of the battery case. Accordingly, it is possible to easily attach and detach the batteries with respect to a vehicle body for charging, protect the batteries, and secure the rigidity of a vehicle body frame.
