I don't really care about how many minutes or kilometers I've traveled. I care more about the amount of exercise. I think I missed that part of the article.
It's just clickbait and a lie, when comparing to the statements in the sources they link.
Both sources are their own news, with both saying it's less exercise on an e-bike. But by the concept of an e-bike, there is the possibility to ride more/longer/farther, which can lead - depending on the extra range - to more exercise, than a bike without motor.
