My impression is based on going down, say, a 4 percent grade on the default 50 percent setting. You coast to a stop instead of accelerating. In 100 percent mode, it seems like you keep your speed even without pedaling. But even a 2 percent grade, in real life, would keep you going without pedaling. I'm not sure, I haven't played around with it all that much.
