Changing the sprockets is interesting, I only need 55 mph max (88km) speed on the roads I travel. I guess regenerative breaking isn't as simple as...

    This looks interesting http://evolvethebike.com/ Maybe a good candidate for a mid drive like Xing, Bafang or GNG vs removing dynamo on front and replace with hub motor and power Harmony off battery and adding a Schlumpf high speed drive ? At least front suspension option would been nice...
