I did a conversion of an Extra-Small 10-speed purple
Specialized last week that is now 35 pounds and has no ugly wires. They are all thru-frame. It is a lithe and lovely bike. The Public C7-i is a great bike to make into a superior electric bike. The gears are internal and it is super comfy. I am converting the men's version today. It is the V7-i and a larger version of the Small British racing green bike shown. What is fun is these bikes out perform the $7400 bikes from stores and they do not look or feel like clunky electric bikes. Smooth. No thrilling surge and lurch associated with the heavy, online only, rear-drive bikes.
