Sperry Rand Tri-Cart

John Plessinger developed a concept for a three-wheel recreational vehicle. The "TriCart" (tm) manufacturing was licensed by the Sperry Rand Corporation which produced about 40,000 units. Unlike later designs, Plessingerís model had the rider sitting "in" the cart instead of "on" it. His design was more stable and much less likely to tip over. Plessinger has since developed a four-wheel vehicle that would under cut the price of currents models on the market priced around $5000. He hopes to license its production to another manufacturer.
