HI. i recently upgraded my mx650 with a 48V throttle, 48V controller (putting out some crazy 80 Amps. I was overvolting my stock 36V 650W motor but within just 1 ride it burnt up. ( i knew this was going to happen) so here were are.. time to upgrade to 48V 1000 W but im not sure what will fit... please help..
For brushed motors the 1000 Watt versions are the most powerful ones made and switching over to a brushless motor is the only way to get a more powerful motor that has the same diameter.
