between 6 and 16 a girl or boy will probably have gone through 4 sizes of bikes. say you buy the good stuff at like 200.00
200 x 4 = 800.00 on bikes between the ages of 6 - 16 they may even go through more sizes, kids at 6 to like 12 grow like a MOFO.
You could probably buy them 80.00 wal-mart bikes every year and still be under the price of 4 good bikes. Thats a STEAL !!
10 bikes for the price of 4 LBS quality bikes.
