Okay. I have ridden bikes a lot but never done much work on them. I am very mechanical and do a lot of my own repairs on cars and engines so I should be able to fix my bike. My problem is, I don't know what the names of the parts are or where to buy them.

Okay, so what do you call the barring system where the pedals rotate. These bearings are shot on my bike. Where can I go to buy these parts and how do I know which ones to buy?

My bike is a Schwinn Men's Trailway 28"/700c Hybrid Bike

The part I think you're referring to is the "bottom bracket" which refers to either the part of the frames where the cranks attach, or the bearing assembly that supports them there.

In general, you can do an internet search for "bicycle parts terminology" or "glossary" or a similar phrase. Then it
s easier if you click on images, which will bring up a number similar to this one.
.

I thought that is what it is called but in the picture you posted, that name is not found. I think it is calling it the "Crankset" in the picture. But, what I need to know is how to know what to buy to replace it with. I have looked and looked for a parts manual for my bike and they don't exist. I find sites with bottom brackets, but I how do I know which one will fit my bike?

Post a pick of your current bottom bracket there are a lot of different types, cartridge, external bearing, press fit etc...
Then advice can be given also measure the width of the shell it goes in

Yes, that particular picture didn't include "bottom bracket", which is one reason I gave it to you straight on.

But there are plenty of glossaries available, and I only used the first one that came up on my search.

FWIW - "crankset" refers to the assembly, including both cranks and the chainring, that turns in the bottom bracket.

As for what kind of bottom bracket you deed, that depends both on your frame, and the cranks you're using.

If you post more detailed info about your bike, maybe including a photo people will be able to give you a more specific answer.

So there is no parts list available then. You have to disassemble and take the part out and measure it to find what you need. I am understanding you correctly?

That appears to be a $250 box store bike.
I'd expect it would have a "standard" British threaded BB shell.
Chances are it's one of the really cheap Chinese BB's. kind of a hybrid cup & cone/cartridge style.

Now to determine the proper length spindle, which is crank dependent.

From Target's site-
"Warranty Description: Lifetime Limited Manufacturer Warranty"

Maybe if you go there and whine a bit.....

Else you'll need at least a crank puller to start.
A pic of the non drive side might allow us to recommend the proper BB removal tool.

Your replacement part will "LIKELY" be similar to this.

I took a look at the Trailway online and I'm betting it's a square taper bottom bracket.

You have several options.

1. Take it apart yourself if you have the tools and are confident on doing this. You tube video's are very helpful ( ). This video makes it look easy, it's not this easy to get the bottom bracket broken (loosened). Once you have the bottom bracket out, it will have the size printed on it. Then you can order a new one in that size from Amazon or other bike stores.

2. Take the bike to a LBS and have them measure and maybe even install a new one for you. Make sure to get the measurement information from them for possible future replacements.

3. Get a proper bottom bracket measuring tool and measure yourself.

FBinNY's diagram is excellent. Perhaps regarding the bottom bracket: it's the part of the frame that holds the bearings (or bearing assembly) that allow the crankset to revolve.

Regarding your trailway, is this the problem?

Thanks guys. I will break it open tomorrow.

In terms of "names of components" I wouldn't trust this at all:

Only thing correct in that picture is the whiskey.

You need a specific puller to get the crank arms off. You can "kludge" them off with wedges, which is what people use when the puller threads are damaged.
