The invention allows a rider to operate a bicycle in a recumbent position, and steer the bicycle using a direct underseat steering system. The recumbent position, compared to the typical upright riding position, greatly reduces air resistance and required effort. The direct underseat steering system is mechanically simple, which makes is less costly to manufacture, and the direct steering system is also less likely than linkage-based systems to be damaged in a crash. The frame geometry allows the manufacturer to use inexpensive materials and techniques, while still providing the rider adequate stiffness and durability.
