Review on 🛴 Flipsky Electric Scooter Motor 6374: Powerful 190kv Brushless Outrunner Motor for Offroad Electric Skateboards, Longboards, Escooters, Ebikes - 3500w, DIY Kit Parts by Justin Ritter

I don't know why but I haven't had good experiences with their engines. This is the second set of motors I've bought from them. I have a 6384 and recently got a 6374. Both sets were delivered with 1 defective motor. Same problem. The shaft of both motors will slip out and you will need to add extra washers to hold them tight. Another issue is that the shaft in 1 motor of each set is defective with 10-13mm of play when it should stay in place (brakes applied). I was told the motors were stock in the US, but that wasn't the case. Delivery took much longer. At this point I doubt I'll get a replacement and I've hardly used them. make some other good products. Their DKTs are great, their VX2 is a really good remote. I think they are a good company but they need to work on quality control. I will contact them for a replacement. This review will be revised based on your response.
