Hi, I made a spreadsheet for calculating how lean angle is affected by tire width and the height of the mass center.
I made this after a discussion on how the low center of gravity of the Livewire compares to other Energica bikes.

The calculations uses simple trigonometry and assume that the tire is circular at the bottom, and ive used 180/55 R17 tire size for reference (ie radius of 90mm), but all that can be changed if anyone wishes to try for themselves.

From the data you can see that if one manages to put the mass center near the wheel axis, you will have to add significant lean angle to achieve the same turn radius and speed as with a mass center near the seat height. If anyone has some insight on what the actual mass center height is for any of the electric brands/bikes, i'd love to hear those..
