Bought this for our oldest for his "Santa present". Opened the box new years eve to put together and it was missing the front wheel. Reached out to the company who collected information and said they would get another wheel out to us. When requesting tracking information, none was provided. Attempted to call back SEVERAL times with no results. Can't even get a hold of customer service line most days. It has been over 2 weeks and still no answers. I will never buy another Yvolution product for any of my 4 children due to lack of interaction with company.
