Yep. That sounds about right.
The 20 kilometers was 72 meters down and 112 meters up. The first 3 km in head wind then 5 kms in side Wind and the last kms in good tail wind.
Also tempereture was 17 celsius and I was pressing moderately hard in the pedals which made med sometimes go above motor cut off and there by save battery. Top speed on my bike is around 30 kmh. My average speed on this trip was 29,1 kmh.
I have once tried to deplete the battery in boost. I went 83 km before it depleted.
Before you us guys go to your dealer and complain remeber my bike is a EU-version which only has 250 watts where yours have 350 which gives you higher top speed but lower range. Also my weight is 70 kgs.
