we have not built anything yet, still researching the whole project.
ONe thing that would have helped people help you more would have been to keep one single project thread, and keep updating the details of what you've already decided on the project, it's requirements, etc. (preferably by editing the first post with taht info, then "bumping" the thread with your new question(s) as a reply to the thread). Then anyone wanting to help could refer to that, and know whether what they might suggest would have any chance of helping you.
Otherwise they have only the very tiny amount of data given in each of your new threads, and don't know you've actually got an ongoing research of a single project spread over a few years, and many threads. There've been a few attempts to help you already, but it is very difficult to do so.
If you like, I can merge your threads together into such a project thread, or you could start one and link all your own old threads in there for the ones relevant to your project.
Are there any hub motors that have a large enough axle that a wire thick enough to run high amperage at low voltage through, so that we can can climb very steep hills with way to much weight????
You can also use high voltage at lower current if the motor is wound for a lower speed, and use smaller wires that way.
As for "large enough" or "thick enough" there's no way to know if there is one that meets your needs without you defining exactly what those needs are, first (which is where a single build/research thread would help people to help you).
So why don't they make hub motors for motorcycles?
AFAICR, they do. There's several threads about them, if you look around the forums. John in CR has tested various types, as have others. There's even thread in the for sale section by a chinese vendor for them. Sorry I don't have any links.
