Re: Is 4.5 too young for a 90 cc ??
I went through the same thing. I have a 4.5 year old and 3 year old boy. I did not want the 4.5 year old to outgrow the 50cc that I was going to purchase. Both ride the battery operated ATV's and Quads and I have four batteries always charging. I bought the 50cc instead of the 90cc for several reasons:
1. They hold their value no matter what. Parents are always looking for them. Just look in the cycle trader publication. Old ones from 1989 are still going for a thousand bucks and you will never have a problem selling them.
2. Once my 4.5 year old outgrows it, I can will it to my 3 year old who will, in all reality, be 4 when he starts to ride.
3. There is a huge physical size difference between the 50 and the 90. I watch my 4.5 on the 50 and he is getting very comforatable with it. He wips around on it with alot of confidence and it getting used to the hand brake concept and throttle acceleration. Conversely, I watch my 7 year old niece on her 90 and she is barely starting to get comfortable with it and still does not shift the gears yet.
4. The 50cc is also direct drive (no gears to shif) and for any kid starting out, this is one less thing to think about.
So I went witht the 50cc an have no regrets whatsoever. Next year, I will by my 4.5 year old (who will be 5.5) a 90cc and will it down to my younger son.
The worst thing you want to do is put your 4.5 year old on a 90cc and have him/her become scared or get intimidated by it and not want to ride at all. Remember, there is a huge difference between mashing on the accelerator of the battery operated quad / ATV and the throttle of a 90cc. Get the 50cc.
