After a bit of a no-bike hiatus we would like to get our older children (ages 9 and 7) new bicycles. We live in a city with access to paved bike trails (and curbs and potholes). The 9 year old would fit a 24 " bike and the 7 yr old is just a hair too short for a 24 and we'd probably get her a 20 inch and give it to her little sister next year.
All the kids bikes at the local shops look like mountain bikes and I just don't see how my 9 year old is going to do 20 to 30 mile rides with those fat knobby tires. The guys at the bike shop tell me it should be no problem but I don't believe them.
My 9 yr old will definitely go off curbs and such so a true road bike is probably not for him.
What would you do?
