I doubt I will get one but I have recently thought about it being a part of a stable of bikes.

If I did get one it I would only want to use the battery on only 5-10 percent of the time so I would want it to be rather on the light side as E-Bikes go. What are some of the lightest E-Bikes around? If I want it to be light would I be better of building one from an existing regular bike frame?
