Last year in the Netherlands more e-bikes were bought than regular bikes. And on average the e-bikes cost twice as much as the regular bikes. What the Dutch have discovered is that an e-bike is more of a substitute for a car rather than for a pedal bike, it's expands the range of running errands up to 10km or 15km while being more convenient and often faster than a car.
This is future of most cities worldwide sooner or later.
