The boys have had their bikes for a couple of years now, but never really paid much attention to them until now. We had to buy Mario a new one though because his knees kept hitting the handle bars. So Diego got Mario's old one and Mario got a new one. And well, they couldn't have bikes without helmets and pads. I think my heart stopped every time they would do this. After they would go up, they would put their feet straight out and glide back down. Almost every time Diego would fall over right as he was slowing down. They did pretty good steering backwards though.
