I'm not talking out of the brochure but from riding it (the larger flywheel, not the brochure). So it matters if one wants more momentum. It provides a better ride. Some spin bikes have larger and heavier flywheels. They're a better ride than the spin bikes with smaller and lighter flywheels. Same physics at work here.
