We used bikes similar to the ones you pictured. All I know is that of the various kid hauling accessories we had, the rear mounted seat was the one we least liked and ended up using very little. By 3 years old I think we had moved them to a "Trail-a-Bike" kind of thing for many rides. I suppose it depends on the distance but they really enjoyed that.
