    3D printed 400mm EDF project

    Bosch mid drive with vesc controller

    In reply to limbs query ; the version i was working is the rare one built for a back pedal braked rear hub and has no freewheel so the kick on was a real problem, for one with a built in freewheel a lower sensor polling frequency and or slower power roll off ramp would be fine.
