Good to know. Have 83mm on my current board and don’t really see the need to go bigger. Someone mentioned there’s not a lot if urethane on the 83, wondering why that would actually be a problem.
Depending on where you ride, 90mm on hubs is helpful against cracks on the road, rocks, gravel etc. If all you ever ride on is smooth, flat roads 83mm is fine.
I have custom built hub motor, Kegel’s on sk3, exactly 10mm urethane. The problem is that the rubber on my drive wheel worns out much faster than the others. But maybe thats with every 1 wheel drive e-board? Don’t have anything to compare.
