Nobody says you need to use lego camera. Obviously, if a camera is defective and it prevents you from making shots you may want a more costly, reliable camera that will not fail on you when you need it. But I can assume that at some point, when you add to the cost of a bike, you no longer buy reliability. You may even reduce reliability as components are getting lighter and more frail and difficult to replace/repair.
