I think that the 9:Zero:7 and On-One Fatty hubs are both made by Chosen. Those ones are 30 POE and have four sealed bearings. The 9:Zero:7s are listed at 368 grams and the On-One weighs around 450 grams (aluminum v. steel freehub body?).

I have about 1000 miles on my Fatty hubs without any issues, but there are a few posts on MTBR by people who have had problems with them.

i ordered mine from dengfu along with the frame and they were just $118.
they do look like the ones on 9 zero 7 website, for 1/3 of the price :).

I ran a pair of those hubs from last February til about three weeks ago.
They were fine until one day a month ago the rear hub's pawls started skipping on a climb. I disassembled the hub, replaced the bearings and the freehub and hoped for the best. It was fine until a climb and more skipping. Upon closer inspection, I had flattened the teeth on the ratchet ring pretty badly.
I relaced a Hope hub into my wheel and e mailed 9zero7. They sent me a new hub which I'll use on my son's bike he's getting for Christmas.
Now... I'm 250 or so pounds and climb everything. I'm actually pretty surprised it lasted as long as it did. I bet if I had proactively changed the bearings, I may have prevented the minute amount of slop that probably allowed the axle to move slightly enough off center to cause the initial skipping.
These hubs are probably better suited to lighter people.

907. I emailed them and then called and left a message. Got no reply from either. They contacted the shop and told him they'd replace the hub after about two weeks. This is their busy season. I had already replaced the hub with a Hope and didn't care either way, but I'm pretty happy they replaced the hub.

I have these hubs coming on a 190mm thru-axle wheel-set from Q2.
Are the bearings hard to remove?
Were the bearings decent quality or should a 230 pound rider should upgrade them right away?

I have to say, the bearings in it were not horrible and were not crunchy or anything when I removed them. The non drive side came right out. The drive side fought me a little. I replaced them with Enduro bearings.
I'm speculating that worn bearings caused the skipping. They never ever did it before, so what could have started to wear? Probably the bearings.

I'm new to fatbikes and don't normally have hub problems. I picked Chosen hubs after reading reports of Hope and Novatec failures.

That failure could be anything from misalignment under load, sticky pawls not retracting properly or crap heat treating. Guess I'll be keeping an eye on the bearings and finding a good low temperature grease for the pawls.

If no one gets back to you with this, I'll have a pair of these hubs in my hands in a few days. I'll measure em up for you.

I did not see a set on E(vil)-Bay of a 150 front and 177 rear, only the 190 rear. Where else can you buy these hubs in red?

I have a question for you all. I have the Night Train bullet 190mm rear bike from BD. I am building new wheels and would like to get these hubs.
The sellers of these hubs always list them as 190/197mm. 190mm as I understand is the OLD, and 190 would be for a QR axle - but 197 is the same 190mm OLD but with a 12mm Thru axle. Does this make sense? I am trying to make sure I don't buy the wrong size and email communication with them has been... difficult.

Not Ebay, but if you buy through AliExpress you can just specify which set you want - it's essentially one listing for the 135/150 - 170/190/197
