Yes, the gear reduction is done in the "gearbox" in those. Some bikes use chains to do the same.

If you have elecreic hub motors there is no room for these between the hub motor and wheel.

So, we appear to agree, there could be a shaft or a chain between the gearbox and the wheel.

Ergo, the existence of an off hub gearbox neither forces nor requires a chain to be used to transfer power.

The arguments for why use a chain Vs why use a shaft are not predicated on the existence of a gearbox.
