@eniko FWIW, once you're capable of the minimal power output (which might take some practice, depending on your hills), it takes less total effort to pedal uphill with a bike than to walk without one. Consider that you won't have to go up the hill fast; you only need to go fast enough to be able to maintain balance — which can be a remarkably low speed. And putting the bike into a low gear to get up a hill is not cheating, either.And after that point, unlike walking, your speed will get higher with practice, too.
