If you don't know please direct me to where I could find out.

Here is the three videos which show you what is wrong with my bike;

http://s84.photobucket.com/albums/k2...ent=144110.flv

http://s84.photobucket.com/albums/k2...ent=145054.flv

http://s84.photobucket.com/albums/k2...ent=145545.flv

...basically, the back tire is 'loose' or something and I need to know what I need to get and how exactly I can fix it because the back tire rubs off against the chain, the actual bicycle frame itself ( the purple part ), and the kickstand. Now, I could probably deal with that, but then since it's loose and not fixed against the frame, i'll apply more force to ride it sometimes it goes in the middle with no resistance so I end up slipping off and my knee'll jerk on the steering bar, or my foot'll jerk off the pedal, and that's not something that can happen when i'm crossing roads with traffic which I have to so I can get to work.
___

Like my subject said, if you don't know please direct me to where I could find out, or even to someone else besides yourself ( if you don't know ) who would know where to direct me.

Thank you very much and i'll hopefully be able to do anything within reason that you would like me to do in return.

Thank you for the pictures. It appears at a minimum you need to replace your bearings, which have probably fallen out. Most likely, a bearing race has disintegrated. Often we just repack them with the appropriate loose bearings and grease. Hopefully your hub has not been damaged, or too damaged. I have repaired them with some scoring, pitting etc. and while not ideal, they have not come back.
My guess it that your seals are gone. We have (I confess) packed them with marine grease and left them open! Very bad, but our customers often do not have the money for more, and often, our shop does not have the parts....Soo.. You would be able to get to work, hopefully, until you can find another wheel.
It also appears your axle may be broken. Take the wheel off and see if the axle comes out in pieces. Good luck!

Holy **** i'm starving i didn't expect it to hurt this much, i'm not going to get chinese food but just some cherios by itself since i don't have milk since i don't have money (cheerios bought by mom somehow). Umm thank you for helping me and showing your appreciation for the 'pictures' that i went through the trouble of getting made available to you.

Please define or show me where i can go to get the best definition (google?) of 'bearings, 'axles', and 'seals'... also whats marine grease and what parts would i need (that ur customers usually don't have money for <-using this detail as extra reference)... and how would i take off the wheel?

Would common sense apply here? IF so i'm pretty sure how, take a wrench and unscrew the thing holding the frame in place... if you would, could you geta picture of a bike and label all the different parts, then pictures of the various tools and parts that i would need to be familiar with to be effective? Please with cherry on top? I'll do anything within reason in return, brb for... 20 mins max

Well, it sounds like you might want to go to your local bike shop (LBS) and have them look at it.

You can take your wheel off with a wrench, but you may have difficulty getting it back on and centered.
Perhaps you might find a bike shop with tools for rent? A good manual is probably available in your library to start. Most people will direct you to the late Sheldon Brown's web pages such as:
http://www.sheldonbrown.com/cone-adjustment.html What I am calling seals, he calls dust caps. His is probably more correct. Anyhow, look at his other pages, and get a manual as well as search threads here on bearing adjustment.

As this sounds like it is your primary transportation your best option may be a new wheel. But whether or not you buy a new one, I'd still suggest trying to fix your old one just so you will how it works. Here is a good place to start:

http://www.parktool.com/repair/readhowto.asp?id=105

For tools, you'll need cone wrenches (Performance Bike Shop has decent wrenches in a 2 pack for $6). For parts, you'll need some bearings (take one of the old ones to a bike shop and they'll get you set up pretty cheap)and some grease (a small tube of white lithium grease from a auto parts store will work fine and is pretty cheap).

Work on an old towel (it will help keep bearings from running away and keep the grease contained) and disassemble, clean, inspect and reassemble with the new bearings. If you've been riding this way a while, the races are probably scored but they'd have to be pretty bad to be unusable. There is a chance the axle is snapped but I really doubt it (if it is, your bike shop can get a replacement).

Basically, you should not be riding the bike the way is is so dive in, take it apart and give it a go. Let us know what you find.

Check out parker tool website. They show how to repair some things. The bad news is that what you are needing to do will require special tools. These tools are probably going to run around $20. A bike shop might be able to look at the wheel and tell you if it is repairable or if a new wheel is in order.

The axle is broken.

At minimum you'll need a freewheel tool, and cones/locknuts/axle and cone wrenches to repair that, assuming the hub cone races aren't signficantly damaged, which is pretty likely.

A new wheel is ~ $50 for a decent entry level one and about $20 labour at a shop to switch everything over. If money is tight look into a place that rents out tools like a volunteer community shop or other.

Get a new wheel. You have either a broken axle, or your bearings have all disappeared. If you've actually been riding this way, you've done nothing good to the hub and it's likely not worth fixing. You may be able to find a cheap wheel for $20 or $30. Try the Park Tools website for removal and installation of the wheel, but it sounds like you may have to eat those Cheerio's a little longer. Sorry.

You can buy a whole used bike in a thrift-store for $25-40 or at garage-sales for $15-30.

No offense, but if you don't know the definitions of bearings, axle, or seal, then you are not a good candidate to fix this yourself. Take it to a bike shop. As the above posters have said, your best option will probably be a replacement wheel (either new or used).

you could go to the bike shop when there not to busy.
ask to see a rear wheel that is threaded for a screw on free wheel
a screw on free wheel.
a set of cone spanners.
a rear axle.
a free wheel remover tool

if you can get shown what the parts are by a person that knows about these things, it will help you.

Also. Is your hub got a plastic centre? A hub should be made of strong stuff to keep the bearings in the right place. Ive got some wheels that have plastic centred hubs. They are truly horrible.

Yeah, seriously, thrift store bike. Find one with the same number of gears in the back. If the new bike is a worse bike than your old one, just swap the back wheel.

I agree with everyone else here: either the bearings are gone, the axle is broken, or both. Once you've solved the problem, take a look in there and see what you can see about how it works. It's too bad that this is one of those hard-to-solve problems. That's a tough way to start learning about how bikes work.

It's awesome that you posted these videos, by the way. Very, very helpful.

+1 Start hitting the thrift stores. Yesterday, one of the local stores around here had two complete bikes for $5 each. I bought one, passed on the other. But this area is cheaper than Long Island for sure.

+1 for garage sales, many have bikes. It seems there are quite a few now that tough times have made people look to old possessions as a source of income.

You might try Craigs too, but you really have to look on there because too many people confuse "old and beat up" with "vintage". If you're looking for a bike worth $50 price, CL sellers seem to think they're worth $200 for some reason.

what one of these ends had gotten loose, at best you will only need to tighten it, but if you have rode it much this way the bearings are likely gone, and the hub parts damaged

If you are desperate it is possible to ride it with out bearings but that will put a death sentence on the hub. if you just tighten up the nuts on the loose side you can cut out some of the play in the wheel and make it "usable".

check out sites like preformance bike, bike nashbar, and jensonusa for replacement parts, tools and new wheels. (jenson has a better selection in those areas)

if you do get new wheels make sure they match your speed.
if you take it to a shop expect nothing cheaper than $60 and it will me more like 70-80.
