Question: can you get a pilot stick  what is the cost?  is it easy to use?
Document: Purchased for grandchildren and both love it. Easy to learn to use, great balance for first timers.Quality is good. Would purchase again.
My 5 year old loves this and finds it easier to use than the mini. Solid and we are certain to enjoy for years and years to come.
Well made, love the easily adjustable handle. Great for bigger kids. We also have the mini that our six yr old got when she was two, but has grown out of and our two yr old son uses now. The quality is great and well worth the price.
This is the 2nd scooter that we have purchased. We have the smaller version for my two year old and purchased this larger model for my 5 year old. They both have picked it up quickly and love to scoot around the neighborhood...
Our four year old outgrew his first scooter and is loving this one! It is well made. Even his Mother can ride it.
For a five year old it only took him 1 day to learn how to ride it. He rides it every day
Best scooter we have owned. Good for all ages, even adults. Holds weight well and goes very fast, turns smoothly and breaks work great! Very well built. Will be buying another for our second child.
