alexibonito that doesn’t look fixable to me but you should contact hiboy customer support for help on this issue they might be able to ship you out replacement parts for that but I don’t know for certain but you will be about a 12 hour wait time before they contact you. I know personally because I own a hiboy S2R and they sent me a new disc brake for free to replace my “defective” ( It stop working like it took about 50 feet for me to stop from 15 mph)
