I am an art school student and am working on a electric scooter design right now and I need a big help.
I need an electric scooter that carries a person (210lb guy), and make 30mph on flat easily and clime on 25% grade hill without stopping.
My first question is that how can I make the scooter possible?
I need to make a performance requirement document first so that I need to know the "power" that requires to carry the 210lb person with that speed. How can I calculate the numbers? What would be the minimum requirement?
And my second question is that which combination of a motor and a battery can make the scooter possible? I know there are many, but if you have any recommendations for the motors or the batteries, I will be appreciated.
As you can tell from my questions (I am aware that the questions are too general, but I have to ask them first to be more specific), I don't know much about physics. I might be too dumb for you guys but please bare with me as I need you guys help badly.
Any input will be appreciated and thanks in advance :)
