Most folders have narrower than normal front hubs,but in the rear it depends on the frame's rear spacing. Most 8+ speed hubs require 135mm,but Sturmey-Archer makes a narrow one specifically for folders/small wheel bikes.

Just the angle of the spokes when building the wheel. Properly done it's not an issue. My old FlyBy had a Nexus 8 and the frame looked similar to the Mu's. There are plenty of EOM and custom folders running IGH's.

Measure the space between the rear dropouts to see what will fit,and just make sure the wheel is built right.
