A belt drive still has the advantage to allow exchange of the transmission ratio online.
Gears require at least to change both sides while exchanging one V pulley and tigthening or loosening the belt tensioner suffices.
This is useful for multiple speed configurable winding motors or when utilizing another motor due to power source speed fluctuations or initial improper match which can not be compensated for by the electronic load and battery controller.
This has to go hand in hand with #8.
