I have all the goodwill in the world for electric bicycles. But I'm not yet convinced that they will ever be able to replace the internal combustion engine.
The reason being, of course, range. And though there have been big battery improvements over the last couple of decades, the state of the art still ain't where it needs to be. And I have a bad feeling that the better batteries of the future might require materials that are more and more rare.
I hope I'm wrong.
But don't throw away your gasoline engine yet.
