Bicycles are currently the most common human-powered vehicles in widespread use today. Their simple, lightweight design remains relatively unchanged. Though motor vehicles are produced in a wide assortment of configurations, pedal vehicles include bikes, tandem bikes, trikes, and quadracycles. Some of these are deficient in respect to safety.

Clearly four wheels are required for car-like stability, hence the “Rhoades Car,” a pedal 4 wheeler produced for many years, but supple suspension and better brakes are required for off-road situations. Two person side-by-side seating, recumbent style, takes advantage of the 4 wheel layout. Independent freewheels for each rider, and a wide choice of gear ratios makes best use of the available human power. This is perhaps one of the last remaining viable forms of the human wheel configuration. Revolutionary and distinctive, this product compares very favorably to the tandem mountain bike in many respects and outperforms it in regard to safety and stability.
