The new motor that should be mentioned in this conversation is the Shengyi SX. It looks like it is similar to the Q128 but with higher efficiency. Anyone have any further data to compare?

All data i've seen on the Shengyi motors shows that they've got good efficiency in small to mid sized geared motors.
The model that ebikes.ca calls the SX2 has something like a 87% peak efficiency and only uses one set of gears to achieve that.
That's more impressive than most dual reduction systems.. both in terms of power density and efficiency.
