Distance differs on the terrain, weight of the cyclist, and the power mode you are using (pedal only, full Throttle, or pedal assist).

For a Single-battery Dolphin: The range is about 25 to 60 miles on a single charge using primarily electric power.
For a Dual-Battery Dolphin: The range is about 40 to 80 miles on a single charge using primarily electric power.
If you use the PAS, mileage can increase.  Some riders can achieve over 60/80miles when cycling in pedal-assist mode.
