A bicycle sprocket assembly comprises a first sprocket and a second sprocket. The first sprocket includes a first sprocket body, first sprocket teeth, and a first pitch circle. The first pitch circle has a first diameter. The second sprocket includes a second sprocket body, second sprocket teeth, and a second pitch circle. The first sprocket teeth include a large-sprocket downshifting tooth and an additional large-sprocket downshifting tooth. The second sprocket teeth include a first small-sprocket downshifting tooth, a second small-sprocket downshifting tooth, a first adjacent tooth, and a second adjacent tooth. A circumferential area is defined from a driving surface of the first adjacent tooth to a non-driving surface of the second adjacent tooth in a driving rotational direction about a rotational center axis when viewed in an axial direction. The large-sprocket downshifting tooth is disposed in the circumferential area when viewed in the axial direction.
