Real Miles per Charge with AT Setup

I am getting about 7 to 9miles with my AT some hills but mostly flats. I was hopeing for at least 12miles. O well I still am happy.

 

This is with an average speed of 13mph, always in fast mode and usually cruising at around 15mph, but I also push start and rarely jam the throttle all the way back. Full throttle starts apparently use the same amount of power no matter what mode you are in. Slow, eco, fast or GT.

 

I can do about 7 miles, before I get kicked into eco mode....I'm pretty heavy and go up some gradients around 8%. My journey home from work is 90% up hill but if I put it in gt mode and use maybe upto 50% throttle I can get home with 40% battery left.

 

And this is why I got a electric mtb using an mbs pro95 with 12s6p monster battery with dual 6375 motors. Can rocket to 35mph and easy cruising at 15mph will go for 20 miles easy!!!
With bindings the carving is unreal.

 

I keep my CGT tires at 50-50psi and I get 16+ On a mixed course (off-road and pavement %20/80 with lots of hard turns, hard braking and accelerating. GT only. I weigh 240lbs. How do some people only get 7 to 10 mi?
