A vehicle with front and rear steering is disclosed. The vehicle can be a cycle. The cycle includes a front wheel steered by a front hand-steering mechanism, and two back wheels steered by a back hand-steering mechanism. The back wheels are dual inclined casters with full rotational movement. A drive train forward of the front wheel drives the front wheel, while a rider is inclined in a seat in a recumbent orientation. The front and rear steering provides unlimited maneuverability and turning capabilities.
