My son really wants a basket for his bike. He doesn't see the use of a rack. Maybe because he doesn't have his own panniers? He has no interest in streamers. My daughter loves the streamers. And polka dots and flowers. But she doesn't want fenders. They are both maniacs on the bell.
My son was coveting a $30 carbon-fiber bottle cage too. I talked him into a $3 aluminum one.
