alt Hacker NewsI bought an entry level ebike and the range is about 100km on lowest power on flat land, and of course it increases if you drive above 25 km/h.
I don't know what the difference is with what op has, but for me it's no extra issue to drive above the top speed. It's a gradient transition.
I use mine daily and charge it every two or three weeks.
The highend ebikes are actually worse at this style of riding with minimal assist, since they are 30 kg behemoths which ride like shit without plenty of motor power.
