LOL...I knew this was over the heads of the "41 Think Tankers"...
Did you see that screen in front of the rider? As they make the adjustments they can look to see outputs. I know, it's complicated and stuff.
I guess that's why they can ride for 6 hours at close to 30 mph and make a real nice living doing it.
Heck, I'm surprised a couple actually had the attention span to watch the video. chuckling...
I love this place,. It never fails to make me smile.
