A few notes on range, some of which you may already be aware of:

- Range is calculated using approximately the last 1.5 miles of riding.

- Range calculation will vary based on what assistance mode you currently have selected.

- Range calculation may be heavily influenced by multiple factors and conditions, ie: temperature, ascent/descent, total weight of eBike+rider, speed, wind, cadence, tire pressure, position on bike (upright vs. aero), condition of bicycle (efficiency), starting/stopping vs. steady speed, etc.

You can reset the range before every ride, but keep in mind it will then have less to base it's estimate on.

If you hang your bike on a rack, turn it "on," and pedal it in the stand very fast... the DU will count that distance traveled and factor in the near zero amount of energy required to cover that distance. You may end up with a unrealistically large residual range.

If you turn your bike on, and pedal slowly up a hill in a low cadence/turbo, the residual range calculation will drop.

Cold batteries will have less range than room temp. or warm batteries.

It is not uncommon to turn the eBike "on" and find a slightly abnormal range calculation, due to any of the factors listed above. That being said, things should begin to normalize with some riding.

The "high" range numbers you listed seem to be at the upper end of what is realistic, though not impossible. Could be caused by finishing your last ride with a long downhill. Could be caused by the rear wheel spinning freely while transporting the bike on a car rack.

Bosch designed the range calculation to be as accurate as possible, and to constantly update, therefore you will likely see the occasional abnormal value displayed. You will also likely continue to see fluctuations. It's definitely different than the "miles to empty" shown in most automobiles that is fairly steady in comparison. There is a much greater ability to influence range and efficiency with an eBike compared to an automobile.

I hope this helps!
