Lennard Zinn (and the art of ____bike maintenance) built one for himself with a nice Bosch motor and you cannot really go after him. He is not some random shmuck and the bike is really nice looking and if he had wanted to he could do the intube batteries from Bosch and really knock it up a notch. If he wasn't so damn tall I would ride that bike. Orbea does the Gain and Focus had the Project Y for a while. Honestly I cannot fault anyone for going electric. My shifting is electric on my road bike and so long as you aren't racing and cheating, go for it. However make sure the bike looks nice, ugly e-bikes are no longer needed with all the great integration out there.
