    What is the lowest "gear inch" I can set up on the NuVinci with a 20" wheel, 22 sprockets on the crank and 44 on the hub. I get 10gi is that right?

    I'm thinking of using an Ecospeed motor with the NuVinci hub gears; would that be slow enough to move the 450lbs up my 16% grade?

    I don't under stand the Ecospeed system, is it really possible to run it at peak efficiency?

    Maybe I need the 500watt motor that is similar, what is its name?
