Ok, so Monday's issues were definitely user error.
Today i rode the full 14km and used two parts of nothing out of the battery voltage.
I have set the Designated Assist Level to be controlled by speed rather than the throttle (Which is now disabled, still not sure what i changed, but it's working.)
My range at 52.9V is showing 149km now.
Today's AAR
Starting battery status: 54.2V
Average speed: 24.7km/h
Most consistent speed seen was around the 38km/h using 7th gear and PAS level 4 of 5
Max speed: 49.7km/h with PAS lvl 5 of 5
Power output of the motor was pretty consistent around 500W the whole way home, i was pretty anal about using the correct gear and PAS level than i was on Monday.
Time per direction around 17 minutes.
Distance travelled: 6.7km to work, and 7.3km home.
Change in elevation in the morning from point A to point B: 29m, almost entirely down hill.
Battery charge when arriving home was 52.9V
All in all, i think this is going to be a great investment for me, it should be saving me around the 70km per week mark in driving, which with my old Subaru Outback equates to around 10L of fuel, or at current prices around $20/w.
If it can do 8,000km it will have paid for itself just in fuel costs.
