The wheels for the go-kart are clones of Honda Passport (scooter) wheels. Under the hood—ahem, or in the back of the vehicle—the car is powered by a 5KW BLDC motor with a sine-wave controller, similar to those used on electric bikes, as well as a 48V LiFePO4 battery pack with integrated battery management. There is also a Grin "cycle analyst" which monitors the system and provides energy consumption information, speed and so forth.
