an internal gear hub with integrated motor, googling seems to come up with lots of variations on geared motors which i'm sure is not the same thing. just wondered if there was a kit that had motor and gears in one unit.
This is available from ebikes.ca and if I'm not mistaken, all their DD motors come with ferrofluid installed as standard now, so they can take more abuse than equivalent non FF cooled motors.There's a motor with an integrated gear-hub. it's basically just a direct drive motor around a hub-gear unit, so a bit of a waste of time.
