Help

My whole back wheel including the motor is kind of pooches and I need a new one anyone know where I can find one it's a kaishan 500ws I can't seem to find any, maybe the one one for a gio pb would work?

Not familiar with Kaishan, but entire kits including controller are fairly cheap on ebay, or ali express. Just make sure not to upgrade the power of the kit too much, or it will kill your battery.
