A fascinating interplay of power and design, engineering and versatility. Optimum comfort and control. This machine is a horse of another color. Combining the best features of a Hannigan Trike and a Hannigan Sidecar, the Tri-Car is a completely new style of three-wheeler. Trikes handle more symmetrically than sidecars, but sidecars have more carrying capacity and offer much more riding comfort for the passengers. The Hannigan Tri-Car offers the best of both worlds.
