At the center of the family story is 13-year-old titular protagonist Madison, for whom cycle racing means just everything! She gives her all to emulate her cool and successful cycle-pro father. But when the talented and ambitious young racer has to unwillingly swap saddles for a mountain bike, things go haywire.

Kim, Franzi, and Marie have what other girls can only dream of: their very own detective club!
