A human powered vehicle comprises a dual wheel front steering, a single or dual wheel rear drive, three or four wheels, a strong lightweight frame assembly, a steering system, two pedals, and a crank and chain transfer drive system. A driver is seated in an upright position for maximum ergonomic efficiency and minimum propulsion effort. Said position also provides for easy mounting and dismounting on to and off of the vehicle. The steering system is completely adjustable and incorporates Ackermann steering geometry to reduce wheel turning scrub and preserve forward momentum. The invention is further configured with components that can be adapted to various manual drive systems, multiple gear ratio drive mechanisms, or power drive system such as an electric motor or similar device. The invention is more easily operated by children, elderly, and the handicapped than bicycles, traditional tricycles, and other three-wheeled human powered vehicles.
