The Grunt packs a 48v 12ah, 800W motor, resulting in plenty of bottom-end torque. This makes them an excellent choice for kids (6 to 12) who want to drive in denser terrain, climb hills, or saddle up with camp gear for a weekend in the wild! The Grunt also comes with the Daymak Drive Turbo Bluetooth Controller that allows you to configure acceleration, increase the range lock the motor and more. All can be done wireless through any smart phone.
