My soon to be 9 yr old daughter has outgrown her 16" toy r us bike. She complains about difficulty going up the hill on our street. I am thinking about getting her a 20" with different speeds because the single speed bike will cause her the same hill problems as before. I definately want to get her a nicer bike from a LBS but I also worry that since summer is almost over and she doesn't ride much in the fall that she will outgrown a 20" bike by next year. Should I want until next year and go for a 24" bike? The 24" is a little too big for her now. Any recommendations as to bike brands. I had a FUJI road bike for many years and had great memories of its durability. How about something like Specialized or Performance? Thanks.
