I have an electric car.
The battery size is 16Kwh (weighs almost a ton)and is far bigger than any bike.

This will take me about 80 miles.

I presume the bike is designed to run out of juice as soon after it
crosses the line as is possible.

So a bike is likely to have around a quarter of this (let's say).
So a bike is likely to need say 4 Kwh per charge.
So each charge up would cost around £0.75

You seem to be thinking about a toy scooter, not something that did this
last year ...

Well there you go.
The bikes battery is 30% the size of mine. (16Kwh)
Ergo the energy capacity is around 16 x 30/100.
So it's around five or six Kwh capacity.
No other information needed, everything else is drivel.
So it'll cost £1.50 per charge if electricity costs £0.25/Kwh
