The invention relates to a three-wheeled electric vehicle (10) comprising a front-axle device (22) having two steerable front wheels (24a, 24b) which are aligned substantially parallel to each other when traveling straight ahead; a rear-axle device (12) with a driven rear wheel (14); and a vehicle frame (26) on which the front-axle device (22) and the rear-axle device (12) are supported; wherein the front-axle device (22) is designed such that when the steering angle is rotated, the vehicle frame (26) and the front wheels (24a, 24b) may be tilted in the direction of the rotated steering angle. The compactness value KW, which is calculated from the ratio of the distance SP between the front wheels (24, 24B) when arranged substantially parallel to each other for a straight-ahead travel to the wheelbase RS between the front wheels (24a, 24b) and the rear wheel (14), said wheelbase being measured when the front wheels (24, 24b) are positioned for a straight-ahead travel, satisfies the following condition: KW=SP/RS 0.35≤KW≤0.80, in particular 0.62≤KW≤0.78.
