A couple of weeks back, after a ride, I normally charged my battery only this time the range on my Bosch Intuvia didn't change. The range at turbo mode read 11 miles, the same as when it started charging. Battery and the display had 5 bars (fully charged). I figured, time for a new battery but it's only 3 years old with about 5000 miles on it. I reset it, but nothing changed. So what the hell, I went for a ride. As I rode, the range mileage INCREASED. After a couple of miles, the range read about 35 miles in turbo mode and then began to decrease, which was normal for the 400 watt capacity. Maybe just a software issue and it's been fine ever since. Very strange.
