Screenshot of my bicycling app during my ride today. A protective case holds it on my handlebar so I can see it. The important number while riding is the blue 30 for fastest speed. When I ride I try to hit 30 at least once. That makes me break a serious sweat and that's want you want during a workout. Just 3 or 5 seconds is enough... for me that is the very maximum of effort that I can make.
