A bicycle hub assembly comprises a hub axle, a hub shell, and a sprocket support body. The sprocket support body includes a tubular part, a first sprocket engaging tooth, and a second sprocket engaging tooth. The tubular part includes an outer peripheral surface and an attachment portion. The first sprocket engaging tooth includes a first radially outer surface provided radially outward of the outer peripheral surface. The second sprocket engaging tooth includes a second radially outer surface and a third radially outer surface. The third radially outer surface is provided radially outward of the outer peripheral surface and radially inward of the second radially outer surface. A first distance is defined from the outer peripheral surface to the first radially outer surface. A second distance is defined from the outer peripheral surface to the third radially outer surface. The second distance is shorter than the first distance.
