Hello everybody!

I'm new to this forum so i'm going to introduce mycelf first.
My name is Aleksey, i live in Riga (Latvia), and I'm restoring old soviet folding bike.
It's not a BMX, but i think it's right place to ask about Skyway tuff wheels...

I'm considering using these on my bike. Always wanted these when I was a kid, but never could get or afford.

So, I want to try to fit hub gear in there (Sram i-motion 3). Well, Cut inside with original hub out, then fabricate custom bushing (aluminium or steel) to fit Sram hub in there. Probably sounds a bit crazy, but I have machine shop available for free. And before buying wheels I want to figure out everything to be sure it's doable.

Can anybody tell me what are the dimensions shown on picture? (20" wheel) I can't find this info anywhere. And there is no shop in Latvia where I can look at those wheels and take measures.
