Perfect for touring through neighborhoods or along the boardwalk, the stable, quad-wheel pedal car has two sets of pedals for multi-person cruising power. Rack-and-pinion steering ensures smooth and easy turns, while disc brakes provide gentle, confident stops. The basket seat securely holds two smaller children who can enjoy the distinction of riding up front, while the padded benches comfortably seat adults and older children."
