….would love to see someone do this. As you say one would need to keep the corner weights the same to keep the same handling experience. I have an i3 (2015) as well and like it very much…the single pedal operation is great fun with regen doing most of the retardation…up to a month or so ago she still had the same brake pads and discs and were only changed because of pitting from lack of use.
Where to put the batteries?
Fuel tank positions obviously
Create a hollow bespoke centre spine to take another battery pack?. No gear change required and minimal cooling which might liberate this area. Range would be an issue but it would be a fun 100 miles!
Anyway good luck to the original poster
