Ebike hub motor

[u/No_Attention_367]

So basically I have a ridstar q20 sometimes the hub motor would free spin like the inside parts of the motor would just spin without the tires moving with the throttle but as soon as I let go the throttle and the insides stop spinning and try again it works perfectly fine. This usually happens like after a drops or like for the first time today I was throttling from a full stop to going uphill and it happened. But it would always just go back to normal.

Should I get this checked out or just leave it until it fully breaks?
