Is replacing parts on a bike easy?

Say in the future a part on my bike goes out would it be easy to buy a replacement part on the internet and switch it out? The crank and casette seem confusing to me because of those cables. I want to save money instead of paying somebody to do it in the future.

Take a course. You can often find an intro course at your LBS or local uni. Some LBSs will hold more extensive courses as well.

And ... what cables are associated with your cranks?

Your might also want to look here: Sheldon Brown
and here: Park Tools. There's a lot of information here about how the parts of the bike go together. Once you start learning, it will seem less mysterious.

You also might want to find a book on bicycle repair. The internet is fine but some times having a hard copy of instructions/explanations/specifications at hand while you are working is helpful. Lennart Zinn writes some very fine general repair manuals. He tells you whats easy for a beginner and what you may want more experience and/or special tools for.

Does your community have a bike repair collective? They would have all the tools you need and someone with experience to assist you...

Depends on the part and the age of the bicycle. I have a 1991 Giant Excursion that is running a 3x7 Shimano Deore drive train, parts are getting harder to find for it. Some things are fairly easy to swap out, others take a bit of hands on experience to make the job go better.

As suggested above, Park Tools website, find a bike co-op or a friend that works on their own bikes, books and online tutorial videos from U-tube are a good way to learn also.

Webshots is bailing out, if you find any of my posts with corrupt picture files and want to see them corrected please let me know. :(

Thanks for that tip, I am a newbie, and didn't know anything about a "bike repair collective".
I can't do anything to a bicycle, or any other mechanical thing for that matter..

After seeing your post, I googled a "bike collective", and put my city and state behind it. Low and behold, they listed a bike collective right in my city. I just subscribed to their newsletter and will be contacting them shortly.

Again, thanks for the info..

Very easy. I learned form reading Sheldon adn Park Tool sites. Now there are youtube videos on just about everything. Heck, I couldn't find a certain issue on my camera in the manual but found how to make the adjustment on youtube!

Very easy if you have the patience to figure it out. Use Youtube to your advantage. I learned by trial and error back in the 90s.

depends on the part... and the bike. anything on a bmx style bike is prety easy to do, for the most part. geared bikes are a bit more complicated, what with gears, derailers, shifters, multiple chainring sizes, casette sizes, etc.

trial and error is great and all, but it goes alot more smoothly with a bit of training.

Yea as said above some parts are easy to replace like pedals and clusters and cranks. Others are a bit tricky. I have learned to do the easy stuff that wears out myself and I get the LBS to replace the more elaborate or rare changes. That way I do the vast majority myself.

I learnt about bicycle mechanics from buying a bicycle component by component and assembling it through trial and error. I'm thankful nothing disastrous happened

One of the most important things to pay attention to when replacing a part is the proper torque values regarding bolts. Not enough torque could lead to disaster.

i learned all most of the stuff i know from trial and error on bikes that i got for free from the trash. i find it difficult to understand some of the stuff i see online unless there are very detailed pictures and even then some parts are different than you see online.

Eventually I'd like to learn to replace the brake pads myself besides really cleaning and maintaining my trike.
