It can hold my and my kids weight and has rack on back. Extra key for parental control of 3 different speeds. I bought brand new from Amazon and it was very difficult for a strong man electric sockets to remove the shipping package. It's state's that 5 years of age and up is suitable, but it depends on previous experience and what speed it's on. I like to go ride on behind because I always wanted one. I take keys out when we stop also when we go up steep hill to turn speed up. It's such an amazing experience for us both. I bought 2, but I'm ready for a bigger one now.
