The bold pattern for the rim ... 4 bolts 5 bolts and the distance between them ... if the wheel is not matching the pattern of the hub then you cannot install or you may need an adapter
Got it, thanks. So the I20N has the same bolt pattern as the I30N and that means we can stick in some nicer wheels?
Any examples? I'm getting a Dragon Red, so a set of copper/gold rims would probably work out nicely.
