A bicycle with a 27-inch rear wheel typically has a wheel diameter of 27 inches, which affects the overall size and performance of the bike. The larger wheel size can provide a smoother ride and better traction, especially for taller riders. It is important to consider the compatibility of other components, such as the frame size and tire width, when choosing a bicycle with a 27-inch rear wheel.
