Surrey, Rhoades Car and American Speedster are among the companies that manufacture four-wheel cycles. Of them, only Rhoades Car calls its products four-wheel bicycles, as "bicycle" implies a vehicle having two wheels.
Surrey distributes its various lines of four-wheel pedal cycles internationally. Its Classic, Deluxe and Italian models all have bench seats and overhead canopies. Surrey markets its cycles for families and for rental businesses. Rhoades Car cycles are manufactured in Tennessee, and the company offers several models of four-wheel cycles. The Go-Boy features a simple four-seat design with no cover, while other models have a variety of top options. American Speedster makes one- to four-person four-wheel models, including "coasters" designed specifically for children.
