Hi
@Hozer, sorry for the long answer, but it is like asking how many revolutions a bowl makes.
Correct answer: it depends! *
There is not enough data to define your maximum range (I assume you mean the range, not how long - years - the battery will last). This depends on
- the route you take: changes in altitude are very relevant with bycicles because they are very efficient in terms of friction loss, so what really counts is any kind of climb, unless you are quite fast.
- Your speed - as a rule of thumb, if you double your speed, your range will be divided by four. If you ride at 25 mph, your range is around 70% of that at 20 mph ( (20 / 25)^2 = 0.68), all other conditions equals.
- Your total weight, including the bike, your clothes, and any accessory you may have with you
- Motor and battery efficiency
- The state of the battery
- Acceleration and braking
- The controller setting, if you have "modes".
- ... do you pedal or not? Not clear from your original message...
Even if you take all this into account, the uncertainties in defining the range would be 10-20%.
Regarding the MAXIMUM range, you can extrapolate it by riding on a flat course at a low speed, with the most economical mode set, until you have used, for example, 20% of the battery (starting from 80% and reaching 60%) and then multiply by five. This is the best I can say. Best way is to refer to the instruction manual of your bike, if any.
With a 2880 kWh battery like yours, I guess that 100 miles are reachable on a flat ground, but maybe 150 or 75.
* Actually, in Italian, it's a typical childrens' joke: one kid ask another, the other seem puzzle and says "I don't know?" and the first one replies "it turns, it turns, until it stops", meaning "nobody can tell". I wonder what the analogue is in English!
