I ride on level 4 most of the time but without the red button. I have an approx 13 mile commute each way with some hills. On level 3 with pedalling it takes me 50 minutes on the clock each way. On level 4 with pedalling it takes me about 45 min. I can do both ways on one charge.
If I would use the red button only I could probably do 12-13 miles at best with one charge and without breaking a sweat but I never tried that. I really like the idea of a stereo blasting Led Zepp - sounds more fun than the headphones
