I see that no one has mentioned this electric bike.
Disclaimer: I have a friend who has invested in this company, which is how I found out about it. I don't have an opinion as to how it performs, but the design stopped me in my tracks the first time I saw one. The batteries are in the frame, and the hubs are the motors.
Here is the company website.
Here is my photo from a bike event where a guy rode in on this one.
