In one of her trips in search of Viravento, Vivi arrives to Amsterdam. While there, Vivi, Backpack and Flashy get to know Vincent, a bicycle that is trying to learn how to ride without the back-up wheels. As Vivi also wants to learn how to ride without the back-up wheels, she asks Backpack to use all of his wisdom to teach them. The problem is that none of Backpack's techniques seems to work.
