I feel it is useful to provide actual numbers on conversations like this.
On some brand I quickly googled[1], the bounding box that covers all of their models for electric bakfiet's size is 253cm x 95cm (with no individual bike being both that long and wide). Comparing them with a Fiat 500 and a RAM truck[2] (just for kicks), that bounding box is 1 meter shorter in both dimensions than the Fiat. And their classic model is 228cm x 63cm.
