Review on Dioche 1000W Motor Brushless Controller 🚲 for E-Bike Scooter - 36V/48V, Sine Wave Technology by William Wiley

The product doesn't work at all in 3rd gear. He slows down and stops. I have experience and several other controllers. I think bad mosfets work fine in 2nd gear though and took about 5 hours to assemble. I should have opened it up before plugging everything in and looking at the mosfets and board, but I just wanted to plug it in and play. I've tried learning on my own a few times to see if that would fix the problem but my wheels are kind of locking up and are weird, like record squeaking/wheel chatter or something
