Home-Built 3 Wheeled Go-Cart
I built this 3-wheeled go-cart equipped with a single 8-in. drive wheel on back and a pair of 6-in. wheels on front. It's stable enough that kids can operate it safely at speeds up to 40 mph. Power is provided by a 4 hp Honda engine, which belt-drives a small sprocket that chain-drives a larger sprocket on the wheel. Steering is accomplished by a cable and pulley steering system connected to bicycle handlebars. Cable wraps around a small pulley at the bottom of the column and extends on either side to the machine's tie rods. Turning the handlebars causes the cable to tighten up on one side of the pulley and lose slack on the other side.
  The seat - designed for a garden tractor - is bolted to a plywood floor that's bolted to an angle iron frame. The driver is protected by a roll cage made out of 1-in. dia., thin wall tubing. The rig has a hitch on back, allowing it to pull wagons and carts. The wide front wheels make it stable, and the single drive wheel on back provides constant traction.
