Where can I find some good sizing guides for kid's road bikes?

I'm doing some research for a friend who wants to buy a bike online (there are no stores nearby that stock kid's bikes so he can't try one out) for his son.

I'd like to find a guide that includes some information regarding height, inseam and bike dimensions/geometry.

If there's anything that explains the relationships to how the physique relates to the geometry of a bike, that would probably be helpful too, even if it's not specific to kids.

Thanks!
If you read the question, you will note that I'm not asking for help sizing a bike to a specific kid. For starters, the guy has 3 kids.

I am looking for guides. Mostly because I don't want to just take someone's word for it, I want to understand WHY a specific size of bike matches a specific size of kid and how it all fits together.

The Sheldon Brown has been excellent as always.

Anything else out there?

How do you remove a valve stem from a bycicle tire?

purplelynn

I don't have the tool that removes the valve stem. Is there something else I can use? I am replacing the tubes in my kids bikes and the box says if the valve stem leaks then take it out and clean it and put it back but I can't get the blasted thing out. Grrr. Can someone help with this.

Answer
You're looking for a valve core remover. They're available at any auto parts store.

FWIW, tubes are cheap, and in 40 years of serious riding, I've never had a valve core leak. Replace the tube. Go to a bike shop or order online from Performance or Nashbar. If you're getting your tubes from Wallyworld or Targét, that could be the problem.

Note to Gerry: Slime tubes will seal small leaks, but eventually will seal the valve as well, making it impossible to pump air in the tire. Tried that once, never again.
