This thing has a great battery life, but also can go pretty quick! My daughter was gifted this from a friend when she turned 7 and I was certain shed be too big (although shes tall, shes petite) and this fits her perfectly. She even has space for my almost 4 year old to sit with her comfortably.There are two speeds, a switch for 2x2, 4x4 and music. Shes even got a switch for lights! The lights arent crazy bright but a cool effect, and also helpful for nighttime and others to see us on the move.Ive charged it maybe 3-4 times in 2 months, and we go on 1.5 mile walks about 4x a week.
