    20" Fat DD, adding FF.

    hello all, I have a 20" Fat DD hub, and I'm looking at putting in so FF I don't know how to determine how much I should put in. looking at the wheel I don't see anything like model number or brand, All it shows is Volts, Wats, Size, and direction of travel. Any ideas?
    just Volts, Wats, Size, and direction of travel...

    That is great decryption, getting "some ferrofluid" out of "so FF". In retrospect, "I don't know how to determine how much I should put in" was a big clue.

    If you add too much ferrofluid, the only penalties are cost and weight. Buy the ferrofluid from here: https://lunacycle.com/luna-ferroflui...-coolant-10ml/

    The product description includes this helpful link: https://www.electricbike.com/ferrofl...-direct-drive/

    Hey Jaxxy, are you talking about adding ferrofluid to your hub motor? If so, go to youtube and type "statorade" into the search box. I found 2 good videos, (1 instructional, 1 real world testing), both by grin technologies. I have no experience with hub motors so I can't help beyond this. Good luck

    I gather that DD is direct drive, but I don't know what FF stands for. Are there any more details that you can add?

    Are you trying to select a system voltage?

    Quite frankly I don't know what you are trying to say.

    well with the lack of responses here, am I right in thinking I should be asking in the " New Builder Questions " insted of here. Dose " electricbike.com " utilize moderators to move threads to the best suited sub-forum ?

    Moderator I would appreciate you moving my question to the best place for it, Thank you.
