Anybody know the name of this "bike/trike/trainer" ??

Has 3 wheels, looks comfy/laid back, steering with hands near hips, legs elevated for pedalling outdoors. Reminds me of a piece of exercise equipment that might be found at the gym, but have seen these "trikes" (??) outside travelling down the street, casual riders and serious training riders. Have searched so many sites on the web and no closer to knowing what this is called.
