I think it’s something related to hall sensors, because in low rpm while it uses them to track motor position the torque is shit but when it’s at speed the torque is normal. Also while it uses the halls the motor doesn’t run as smooth as say flipsky or 6368 motors
You can also adjust the throttle curve to 20% or 30%.
Makes it more responsive and torque feels much better from low speeds.
Edit: Motor vibration is bc of too much amsp for these motors i bet…What number tells the detection? How much amps? Dont raise this value and vibration is gone.
