This astounding figure is reached only if you charge your ebike battery via a solar panel. Otherwise, the equivalent mileage goes down to around 500 mpg. Not shabby! I assume those numbers are reached via a math formula that takes into account all the energy expenditure in getting to the point of riding your electric bike: manufacture, electrical generation and distribution, calories spent, etc.

The question is, What is the formula? What are the assumptions and what are the calculations? I've googled this question to no avail. It's not that I doubt the figures, it's just that I want to understand them well.

Thanks in advance!
