How about a video pointing out basic parts of the bicycle, what they are called, and what they do?

When I took a bike repair class, this was covered in the first session, and I found it very helpful. Even though I knew most of the information, I didn't know all of it. At least in the class situation, it definitely reinforced the "beginners welcome here" message. I'm not sure if it's needed on your web site which presumably attracts mostly experienced bikers, but it's probably worth considering.
