For me you get best of both. With the controller you don't have to mess much with the app on the phone. You set what you want on the phone a save it. Then you use the controller to shift when YOU want. You have to try it yourself to really appreciate it.Why buy this bike if you don’t want automatic shifting? You could get the non-IGH Vado 5, or the non-automatic Vado 3 IGH.
