My 20mo old LOVES riding in the iBert. I highly recommend it over a rear seat. It allows interaction and communication with my son, and I can hear his laughs and "weeee's" easier. He gets to be involved with the sights and sounds of cycling, without obstruction (like a rear child seat..or a car seat). I find it safer too, if we're gonna fall, I can wrap my arms around and sheild him. Plus the best part...I have an automatic bell and lights
