When I first got my Level 3, I used Turbo mode and could really fly around on the country roads. I could keep a 22 mph average on a 12 mile ride.
I thought this was great, and for me, it probably helped get me used to the bike.
Then I did the same thing on a 25 mile ride, and it really ran the battery down. I didn't have to pedal (or walk ) home, but I was down to 9% battery.
That was a watershed moment for me, and now I run in Eco mode most of the time, and only use Sport mode to help up some of the bigger hills.
Yesterday I had a really nice early morning Fourth of July ride of 28 miles using my new method of Eco and Sport modes only, and I returned home with 57% battery life. I actually feel like I'm getting a good bit of exercise.
I'm not always the quickest to pick things up, but I am trainable......
