How old should your child be able to ride a two wheeler?

I didn't learn till I was seven and the only reason that I learned was because my big brother practically forced me to. I'm 19 and have absolutly no interest in riding....I'll go out of my way to avoid it actually. I know how and I have a really nice bike but I absolutly hate it. I wouldn't be worried about your son, every kid develops interests at their own paces and bikes just aren't for everyone.

i dont think u shud worry abt it..kids have their on brains personalities and interests as long as he is interested in physical activities u need not worry abt what they are

Ammm... most of the people I know started when they were six or seven.
