The Bulldog is a giant 1/3 scale, gasoline-powered, radio control truck which can be converted to run like a compact four wheel ATV, launched recently at Dealer Expo 2009.
The truck runs on a 110 CC four stroke single cylinder engine and is controlled remotely by a 2.4 GHz radio transmitter, but when you're done playing from a distance, attach the handlebars and nerf bars and go for a ride. The tube frame and four wheel independent suspension makes sure an entertaining is is designed to carry a seated full grown man, who will be giggling like a little kid the whole ride.
