Ive just got my bike going after a two month battle plus me not knowing very much about motorized bicycles is been rough. Friday night I went for a ride because I knew it was going to rain all weekend so about 2 miles out bike starts to feel funny looked the boke over everything seemed of so I started to pedal and there was alot of resistance so I seen something on the rear wheel the rotor was lose and sproket I pushed it back 2 miles the next day yesterday I removed the back tire and wheel and seen this sorry for the bsd pics Im going to try to get some better ones the rear wheel was the only damn thing that come assembled its unbelivable that was sold to me like that. What do I do to fix it? Oh thats the bolts that were in it there stripped out as well. As far as I cincered these felt fakers are crap.

Did it strip the threads on the hub?

Bummer. First lesson, you have to check all the fasteners all the time. Every ride. Even if you just go around and tap them with a wrench. If they make a clunk sound rather than a ring sound they need attention.
I dont know yet ill have to wait till tomorrow when the hardware store is open so i can get some more screws they all are bent or striped.
Dully noted and Ill put red locktite on them.

Use blue lock-tite, keeps it secure but lets you pull it apart if it needs repair.
I took some pictures of that side of the wheel. What Id like to know is that all there is to it? Another question I didnt count but I think it was either a 32 or 36 tooth sproket max speed is not something Im interested in but take off low end touque so Id rather have a 44 or 46 tooth sproket but there isnt enough bolt holes on whatever that aluminum star piece is in the pics.Oh also there was alot of metal shavings all over but I cant figure out where they came from.

That aluminum "star" piece is just a spacer, nothing fancy about it. It is easy to replace and can be found pretty much anywhere as they are used on many disc brake bikes to set spacing for the rotor off the hub. They come in different thicknesses for that reason.
As far as the metal shavings go, looking at that spacer in your hand, I want to say it looks like some came from that. It looks damaged, like something ground away at part of it. Take a magnet to the shavings and see if they stick to it and that will at least tell you if they are aluminum or steel. From there you can look at parts of those metal types, see what is damaged, and draw a likely accurate conclusion. I would say most of it is aluminum, and likely from either that spacer, the hub, or both. I don't see any catastrophic damage in any of the pictures (from what I can see at least).
Go get a bottle of medium strength (usually blue) loctite, and once you sort this out, go over every other bolt on that bike that can be a safety concern. If you don't know what I mean by that, have a sit down on said bike and think to yourself "If I used ____ part and a bolt had fallen out, would I crash and get hurt or die?" and then add said loctite.

Great Idea of the magnet Ill do that tomorrow and yes i have strained the brain and went through almost a tube of the blue loctite.
Dang a magnet I didnt think about that great Idea and yes I have done a mental check on all the bolts theres blue all over it. Thank you sir.
