This came very quickly, I was quite pleased with that. The motor is amazing. I upgraded my go kart from a 72V 3000W motor to this 72V 5000W motor and the difference is night and day. The heat sensor and ability to use the far drive app on my phone is an added benefit.

But the performance of the motor is so amazing, it dwarfs those minor issues. ... show more
