I have to thank the article's author (or the website editor, perhaps) for the headline. I absolutely loved the phrase “clean, green, hauling machine” so I borrowed it. But I still didn't really know what the heck this little bike-with-a-bucket was all about. 

Now I get it. It's a “cargo bike” with an electric motor. In the author's case, he's using it as his daily vehicle for everything from school drop-offs to grocery shopping to hauling building materials. 

That's one tough bike. And it's environmentally friendly.
