Why didn't I think of that?...
Maybe because I have absolutely no idea what is going on is that photo!
I guess this is some sort of wacky motor for you bike. But I'm not totally sure because the photos on the website are too much for my Miller Lite and Wu Tang Clan addled brain. The "Rural Roads With Roger" video is awesome though.
