And what happens when you run out of power mid ride? Or you get some failure that causes intermittent cut out (corrosion on the connectors, etc)? You've more or less turned your bike into a 30kg dead weight that happens to have the shape of a bicycle and have to carry it the rest of the way vs just pushing it. Or worse, a bike that brakes on it's own without warning. Like I said, what is the real advantage here trying to go wireless here that makes it worth the cost of loosing advantages of a mechanical or hydraulic system? I could maybe see some advantage of a full brake by wire system over mechanical or hydraulic, but wireless? The weight savings aren't that significant.
