Hi

All Wh/km have been tested over 10km of flat road no wind and in both directions. the result is the average between both and is calculated by taking the total Wh spent to acheive 20km and divided by 20.

The range is calculated by taking the Zero publiished nominal battery energy / wh/km for each speed.  easy, simple and real.

I also indicated witch colum is MEASURED wh/km and the other colum is the best fit curve that match all datapoint and i extracted the formula o fthat curve and used it to fill all non measured speed.

I also tested with my previous Ds 2011( brushed motor  and my 2015 at 66V ( using the 2012 battery and 75-7 2013+ motor) and surprizingly  they match very well. someone also said that for speed under 120kmh the 66V and 102V battery give identical results. that is due to the controller still runnning in the non field weakening region. Then at speed above that it start to drift a bit.
