Recumbent tricycles are serious tricycles for grownups.  They work in an identical fashion to recumbent bicycles, except they have 3 wheels rather than two.  There are two main styles of recumbent bikes, the delta which features 2 wheels in the rear and the tadpole which puts two wheels in the front.   

There are many benefits to employing a recumbent tricycle.  One advantage is that you may use a very low gear which makes it easier to climb mountains at a slow speed without a loss in stability.  Recumbent tricycles also let you keep both wheels on the pedals when you come to a stop since they won’t tip over like bicycles.  Another clever feature to these tricycles is they can make pointy turns without leaning.  Due to their improved stability they are a good choice for anyone who has balance or limb challenges.   

One of the earliest models of recumbent tricycles was the Windcheetah, which used a tadpole design.  This tricycle has been so successful that it is still in production today and has a classic design that is enjoyed by many riders.  This tricycle was designed by Mike Burrows who has a long list of designing successful bikes for Giant and is a world famous bicycle designer. 

nowadays there are lots of different styles of recumbent tricycle available, though they are still harder to find than recumbent cycles.  They seem to be a great option for long distance touring since they employ a seat which is designed to hold a hundred percent of the riders weight.  Tadpole recumbent tricycles tend to be more aerodynamic because the rider is seated lower.  They also tend to have a greater gear range than delta models.  One of the most important reasons many riders have for picking recumbent tricycles are their capability to climb just about any slope of hill in the right gear because you do not need to fret about balance.
