This does fit in the front fork I have pictured there. I can check to see if it fits in my Luna fat front fork (which holds a regular rear wheel with cluster just fine, so it probably holds this too). So as long as your fat front fork is like I expect, a 135mm, then it should fit in there. I'll check and post as soon as get this verified.
I would guess it is going to be very expensive to ship to you from Phoenix, AZ, USA 85051. It has a tire and tube now, if you want those too (I doubt I'll ever use them on anything else; it's the only fat wheel I have). If you don't want the gear cluster on it I can take that off to save a little shipping weight (but most of the cost is probably the size of the wheel). If all you want is the motor I can unlace it from the wheel.
(And even more expensive for you to ship batteries to me, so money would probably be cheaper for you to send :lol: and I could use money much more than batteries right now)
