It is when the vehicle is small & light like this.
Heat engines get more efficient with increasing size. Piston count can be increased (improving balance), or piston displacement can be increased (reducing friction, heat loss & gas leakage per unit volume)
Batteries on the other hand get better with decreasing scale, the net distance from source to sink is decreased so it needs less wire. The total number of elements is reduced so risk of fire is as well. The battery is more replaceable, so aging is less of a concern.
Range compounds the effect. Typically smaller vehicles have smaller ranges, and that's good for electric where the engine is much lighter than the fuel, but bad for ICE, where the engine is a massive brick of iron and the fuel can just be a couple jerry cans slung on the back
In cars, the trade-off is a hotly contested race, but you don't see many diesel skateboards or battery-powered containerships.
