QS / Quan Shun, 205/50H V3 "Extra Type"
The QS motor company has also decided to begin selling their E-motorcycle hubs with axles that that have been modified to fit a bicycle. 
Their motor phase wires are thicker than the other motors listed, and their axle design is stronger. 
The stator width is 50mm, but also…the stator-teeth slots are deeper for more copper-fill, and all of this adds up to a motor that can take more watts.
