I dont get ebikes. Surely the extra weight of a motor + battery offsets any advantages. Whats a more efficient source of work than the human body? I average about 25kph on my road bike, on extremely hilly/crappy roads out where I live. I've gone over 70kph on it, but I would very rarely do that as it would be dangerously fast in most situations. If you cycle in and out to work every day your performance will increase as you get fitter / build up certain muscles. Cycling is an elegant, low carbon, solution to commuting + getting enough exercise.
