According to leaf bike, the 7 speed freewheel version of the 35mm is actually 137mm and the cassette version is 140mm....(both with dishing offsets and the cassette version having the largest dishing offset of the two)....but the single speed version of the 35mm is a true 135mm and centered perfectly in the middle making a dish-less wheel.
So it looks like to me this 35mm motor was designed around single speed as the primary goal with the multi gear versions being an afterthought. This, in contrast, to the original nine continent 27mm motor where the multi speed freewheel version was true 135mm and centered on the axle for a dish-less wheel (though with a narrow distance of only 28mm* between the spoke flanges).
* This, in contrast, to the 40mm distance between spoke flanges for the 35mm single speed leaf on 135mm and the 50mm distance between flanges for the 42mm single speed leaf on 135mm. Note: 42mm single speed on 135mm also makes for a dish-less wheel but does sacrifice the use of disc brake.
