This e-motorcycle is certainly a well thought build from scratch.
However, the OP title contains the word “ebike”. The vehicle was not made from a bicycle nor does it have pedals, hence it is not an ebike.
This e-motorcycle build/posting by the current rules of this forum belongs in the section Electric Scooters/Motorcycles.
All the Sur Ron material and likes was moved from Electric Bicycles to Electric Scooters/Motorcycles because these vehicles come without pedals and were not made from a bicycle.
So, I do not understand why this build remains in the ebike stories.
