I was cruising my board the other day when I suddenly noticed this weird noise when trying to accelerate. It is much more noticeable when climbing hills, even not that stiff. It sounds like the belt is slipping but i’m not sure. I tried to tighten the belt, change the belt to a new one and even to a shorter one, tighten the motor and wheel pulley bolts and not luck. My setup: 50mm single motor, 36\12T 5M 10mm, 6s battery, 150a esc.
Help will be appreciated.
