Help with proper hub assembly

I have a custom built motovox I been working on. I’m putting a custom rear swing arm on it with a 14” 850 lb dirt bike tire. Now I wanna run dirt bike wheels on it but I can’t seem to figure out exactly what hub I need to find to adapt the wheel to work with a disc brake and sprocket. Any help would be appreciated!


Really? Look no disrespect but that’s not what I’m going for here! But thanks.
And sorry I meant it has a dirt bike rear spring not tire
Are you sure now you are asking the correct question, I answered your question as you posted it, you said tire.You sound like you are in over your head…
It would be far easier to adapt the dirt bike swing arm as a whole( wheel,axle,disc brakes with mounting brackets, caliper)to the mini bike frame and not re-engineer parts unless you have access to a machine shop.
A picture is worth a thousand words, especially went you are not articulating correctly…
