The speed controller is stepless and is controlled via a potentiometer to the PCB.
If the speed controller falters, it is possible that the potentiometer has a malfunction and we will renew it.
If the speed controller no longer works, it may be a malfunction in the printed circuit board or potentiometer. In that case we can possibly replace both parts. Send an email to info@golfTed.nl with the problem and then an email will follow how we will arrange that.
