You are perfectly right: its possible to be lightweight with at least 3 current compact mid-drive motor that weight 2kg or less (TQ HPR50, Fazua Ride 60 or 50 and Bosch Performance Line SX/Sprint) and a battery below 400Wh that weight 2kg or less (with the latest cell size. Batteries of all manufacturers weight more or less the same, the weight difference come from the cell assembly system and protection against water/humidity, vibrations, shock, drop test and the fact that its UL certified or not).
But indeed, as far as I know, there are no bike manufacturer that use any of those in a folding bike, they are mainly used in lightweight eMTB or eRoad bikes.
The reason could be that these 3 systems are relatively expensive, they fit for the lightweight eMTB and eRoad market since these bikes costs a lot of money, but too expensive for the folding bike market?
Indeed, the "trick" to be lightweight is to use a fast spinning, small motor with an internal reduction that bring the rotational speed to the pedaling cadence of a cyclist.
