I took the Hacker Q100 (38mm stator) on the shortlist for a middrive setup.
The problem (aside from the price
) i see is there is no axle coming out on the backside where a sprocket can be mounted to.
bionicon, how did you manage to install such on your Q150? On one photo i can see a small solid axle with another bearing.
A few more pics would be nice to see.
and how do you like the HST controller?
The small Herkules 5 seems to be AWESEOM from the specs. True FOC 4-quadrant control, hall sensor input etc etc. What a nice 2kW+ controller, but certainly out of my budget...
