Don't forget size of the rider. It gets complicated, doesn't it. Suppose we decide that people over 6'2" (188 cm) tall really need to be riding 30" wheels. Should we make a new standard for them? Should adults buy bikes sized not just in frame sizes but wheel sizes? I hope not. It's bad enough that there are 12", 16", 20", and 24" wheels for kids.
And have you ever noticed how bad most 24"-wheeled kids bikes are? I'd try to keep a kid on a 20" bike as long as possible until she's ready for 26".
