a few years ago...a long time ago. my uncle salvaged parts and put this bike together. i was wondering what type it is. ive been getting into bmx and i dont know if this bike just isnt right for it or what. anyone know what type of bike or what type of frame it is. wheelie is like impossible on it.

Looks like a BMX bike to me. The gearing it has might make it hard to do a wheelie, you would want to get either a smaller chainring or a freewheel with more teeth.
I'm no expert on BMX, but I'd guess that frame is made for racing, not doing tricks. What exactly do you mean when you say you are getting into BMX?

so me and my uncle built that bike ten years ago from spare bike parts. its fun to ride because it doesnt have the smallness of most bmx bikes and it has some of the bigness of the mountain bike. its a good mix but recently i have gotten some free time off from going to college and i have been learning how to ride my bike better. wheelies, bunnyhops, ect. The thing is, that bike is hard to do anything. how would the chain effect my ability to do anything?
Its not the chain but the gears. The front chainring is really big, which means you would have a really fast top speed in a sprint. A smaller front chainring would make it have more torque, then you could do your wheelies.
As far as the bike i.d. The picture isnt very cool and its hard to see any details that may tell us what make/model the bike is. Try a new picture with better lighting and maybe we can help ya.

Not certain I understand what you mean by that.
..how would the chain effect my ability to do anything?
The chain as such doen't affect anything - assuming it's runnning OK. The gearing OTOH will be quite important. Small sprocket/big chainwheel will give you a higher top speed, while small chainring/big sprocket will make it easier to get going.
Although pulling wheelies (on a BMX) is more about body position than gears, a low gear will certainly help getting the front wheel up.
Seeing that it has a rear brake only that bike was probably intended as a race BMX, so it might well be geared a bit more for speed.

Classic BMX ratio, 44/16, which is pretty much the same as the "modern" 25/9 ratio that freestyle BMXers use nowadays. As dabac stated, weight distribution is key.
I wouldn't do anything extreme with that bike though, not sure if the wheels are tensioned, stem/goose neck is tight enough, greased drive train, etc etc. Give it a minor tune up before you do anything serious.

That's an RV, Clark.

Hard to tell, but looks like a MTB frame with BMX sized wheels and fork. The longer wheelbase might make it more difficult to do wheelies. What does it say on the frame? Can you measure the frame's top tube?
