I don't know if this is a tutorial request more than just simply an idea for a feature on the site. Is there a way to get a good list of typical problems and suggested responses (or a good list of them somewhere already)? Or would this be something more garnered towards experience than a checklist?
Why is it that they make adult bikes that'll generally work for 5'9" or above, yet when you pedal these same bikes they only work for someone who is 5'4" or so?
That's a great idea. I've been wanting to arrange the tutorials in a more intuitive way, but it's not going to be that easy until I have all of the major topics covered. I'm currently rebuilding the site which should help some...
I would think it would help to highlight some of the basic things that may have not been covered if it does anything. To simplify it, I would figure most would rather ride their bikes than work on them if anything. So for example, I'm sure most wouldn't want to overhaul their wheel hubs just for the sake of doing it. So I guess the simple question to answer is "Why would I want to do it?" Which I guess leads to the troubleshooting question.

I haven't made many troubleshooting videos yet, but I do plan to. There are still so many to make. As for wheel bearings, you'll want to overhaul them if your bearings are worn. Here's a video that shows <a href="http://bikeride.com/check-bearing-wear/">how to check</a>!
