My little granddaughter just turned six in Italy.  She has big brother's who skate board and ride Razor Scooters-she had to have one but it had to be pink.  She is a Little Princess-everything needs to be pink.  I know she will love it because Razor is the best!  I have purchased several for my five grandchildren.  I love that they fold also.  If the child is young-I would suggest a three wheel for balance.  It all depends on the child.  They also need to wear head gear.  That is a must!
