When I was a kid, I tore around on a cart/minibike combination that was sold by Montgomery-Wards. It was a "early" three wheeler. It had large balloon tires on the back and a minibike type front end. It was powered by a Briggs 5 hp. , comet centrifigal belt clutch, and had a hand brake. It was bright green so it was aptly named "the green machine". Does anyone know who made it for MW? I still have it and am going to fix it up for my nephews and eventually my daughter to drive and of course fix. Good experience and simple. It really was a lot of fun and didn't cost an arm and a leg like the new 4 wheelers. Does anyone remember theses things? What were you riding/driving when you were a kid?
