Based on a 160 lb (72 kg) rider the default battery has a range of 18 KM or 11 Miles. This can be increased to a range of 28 KM or 17 Miles if you select the Extended Range Battery.
Rider weight and terrain can make the range fluctuate. Road conditions, weight, and wind resistance affect the range the most. If you ride slower, you get more range, if you brake less, you get more range.
