I bought my Taiwanese Econelo e-roller from Netto for 1.400 €. I can take out the 5kg battery and carry it upstairs to charge, but I also put down a charging cable from my kitchen to the parking lot. When driving around I have the charger with me, and I usually charge at work also for 2hrs. Because the range is only 40km now.
