Abstract: A bicycle crank assembly has a sprocket, a first crank arm, a second crank arm and a crank axle, A first axial distance is defined between the first pedal attachment surface and the second pedal attachment surface in an axial direction. A second axial distance is defined between the first transverse center plane of the sprocket and the second axial center plane of the crank axle in the axial direction. The first axial distance is smaller than or equal to 170 mm. The second axial distance is larger than or equal to 55 mm.
