The English Wikipedia doesn't include this snippet of history, the Italian page does though https://it.wikipedia.org/wiki/ACMA_Vespa_400
Piaggio also designed the Ape (bee) https://en.wikipedia.org/wiki/Piaggio_Ape a 3 wheel tiny pickup. It was hugely popular, but of course not as much as the Vespa because of the smaller market. I still see some of them especially in country areas.
