We love this bike! We bought it for our tall 4.5 year old son, and he always wants to be outside and ridding his bike. The brakes work great and are easy for him to squeeze on his own. The seat adjusts but the handle bars do not, and I wish they did. It’s very light weight - which is a big deal for me...some bikes are ridiculously heavy for a small child to handle. But, this bike is just the right weight and size for a kid
