I'm liking this thread for all of the effort that is being thrown at explaining motor design, and ultimately, performance in all these different ways. It helps a semi-noob like myself.
So how about this conundrum. Say a person purchased a low turn count, 'fast'-wind motor that is small (rated at 250W; whatever that means
) and mistakenly decided to lace it to a large wheel (say a 700c). He finds out that 12S and 30A is horribly tuned for this setup. He doesn't want a smaller wheel because his bike would look stupid with a 700c front and a 20" rear and the geometry would be awful. Should he try to parallel his packs down to 6S (and modify controller LVC to suit) and turn the battery amps up to 60A or even 100A?
