The ebike world isn't getting away with calling this a bicycle. This was a custom designed mid-drive made by a crazy guy that wanted to shred offroad. This contraption would never pass any legal certification for an ebike. I don't think he made more than a few hundred of these before he stopped making them. In fact that was part of the reason I switched to a small hub. It was lots of fun but both illegal and unsafe. Going over 55kph at the push of a button is not something you want long-term. Accidents happen and the energy the body has to absorb coming to a stop grows exponentially with speed so...

E: The most powerful version was 6KW. Here's a guy riding it, limited to 4KW.
