This little bike shipped incredibly fast, and it is a huge hit at our house already! My son loves the big wheels, and actually prefers to push it around from the front. I initially thought it was defective because the handlebar portion kept coming apart from the wheels, but I just had it backwards. The body of the bike is metal and it is nice and heavy so it is pretty hard to tip over. Luckily, the wheels are a soft rubber, so when he runs it into the walls and cabinets it doesn't damage anything or leave marks. He is 32 inches tall, and the seat is too low in its lowest position, so it could definitely work for shorter or smaller toddlers.
