Interesting. Some were single speed hubs that just used it as a reduction while others had a variator.
Some mopeds had internally geared hubs.

There were lots of interesting designs. There used to be alot of different features in things.

Specifics to exactly what models you're talking about would be helpful

I am in the middle of researching this and info is scarce but I do know that the Piaggio Ciao has something crazy going on in it.

After reading and looking around it seems it was just used a gear reduction with some models having the rear clutch of a torque converter internal to the wheel.
The Caios are Sweet bikes!
Mine and probably 90% of them had a fixed belt and pulley setup with the gear reduction being a separate unit from the moped. Its either a 2 gear or a 5-gear reduction setup that was cast into the wheel, basically just a bigger hub to account for that space.
Single-speed Europe and Ohio you got the 14:1 gear ratio to limit the top speed to around 20-25mph. then you got the 7:1 for the higher top end (basically everywhere else)
the variated versions were about 11-12:1 with the only difference being a different shaft for the variated models.
