This is my sons second balanc bike, but by far the best one! I love the fact it comes with two seats, as he is almost ready for the larger one. I love the ease of the adjustments on the seat and handle bars. Love that I can add a break! This bike with grow with him! The only down falls I've seen so far is one, the bike frame scrapes on a curb when he goes on and off the side walk so after only a couple weeks it has scraped off the paint. And the other thing are the blots that hold the back wheel on hit my sons legs or feet when he's moving along. At first it bothered him but he quickly learned to not hit it and now it's not an issue, I wouldn't let this part of my review deter you from getting a strider bike! Overall my son and I both LOVE this bike!! he rides it every single day, either in the house or outside!
