Question: what is the recommended age group? How short do handle bars go? Is it too tall for a short nine year old girl?
Document: I just did not realize that this scooter was not adjustable. My grandson is quite tall for his age and although he is five, this scooter is too short for him. Would be great if the handle bar height could be adjusted.
My son, who is 10 years old and loves to scooter, was so excited when we got this. It didn't take very long for the handle bars to become loose which we kept trying to tighten. Finally, the welding broke and the handle bars came off. We were very disappointed with the quality of this item.
My son had this scoter for one week the handle bars got stuck and a repair guy could not fix it this is a crappy scooter DON'T BUY
My 11 year old son loves this scooter although he did change the grips on it. It is a good scooter for kids just starting to ride.
It was incredibly easy to assemble, and other than a few little rattles, does exactly what it needs to do -- gets my 7 year old up & down the street to his neighbor friends' houses.
My 6 year old daughter rides this to school everyday and it is holding up great. She has lots of fun riding it and the bright colors draw lots of attention from her friends.
It's an O.K. scooter but I suggest this to beginner scooters. it's not very good for big things. I gaped a 3foot drop and the back bearings broke. the handle bars shake to much. but other than that it's a good scooter.
I purchased this for under $20 for my 7 year old because he's always twisting the handles on his Razor scooter, so this is the &#34;back up&#34;. I really like the &#34;grit&#34; that is on the full deck, and the handles are really cushy.
My kids wanted non-folding scooters because folding scooters have a tendency to break or get loose after hard use (falling off curbs is an example of "hard use").This scooter was perfect for them! My 9 year old assembled it under the guidance of his 12 year old brother in about 5 minutes.
My son loves this scooter. I would say go with the upgrade. For the price the quality difference is amazing, but my son loves it.
