The Ezee is a geared hub with an internal freewheeling clutch, so when the motor is not being powered, it does not drag the wheel.Daveades wrote: ↑Dec 10 2019 6:31pmI have an Ezee rear hub,
In October the my original motor was replaced with a new Ezee
What I am trying to do is get the motor to spin freely when the assist cuts out at about 50 kmh on the downhill sprints. I don't need the motor to sustain the speed but I need it to not the drag that is holding me back.
If it *is* dragging the wheel anyway, then the clutch is siezed, and would need to be serviced or replaced.
Flip the bike upside down, wheel off ground, and hand-spin the tire in the direction of normal travel. It should freely spin, not quite as freely as a regular bike wheel, but close.
Now hand-spin the tire the other way, backwards. It should have a fair bit of drag, because now it's spinning the motor inside, thru the clutch and the planetary gears.
If those are not the behaviors you see, something is wrong inside the motor.
I can't help with the Field Weakening stuff; don't know about it.
THe freewheeling option in the PR should be ablet to feed just enough current to negate the drag of whatever motor you use, but you don't need it with a motor like the Ezee that is already freewheeling internally.
