This is a folding tandem which my wife and I purchased for use during our honeymoon (might sell it afterwords or might keep it for future trips, haven't decided yet). We bought it used, originally it was built by Green Gear for a 1995 review of the Tandem Two'sday by Bicycling magazine. The bike is quite different due to its very low frame and use of 20" wheels, but it rides very well. The gearing of this bike in particular is much different then the gearing of bikes with larger wheels. I address this in an article comparing the Sachs 3x7 and triple chainring systems.
More information on how this bike folds and information on the current models can be found at Green Gear's website.

This bike has a custom 11-34 cassette. I built it by taking a stock Shimano 11-30 cassette and replacing the 26 with a 28 and the 30 with a 34. This gives a nice range, pretty tight gearing on the low end of the cassette, and a nice bailout gear at the top. I prefer the gearing a little bit over the stock 11-34 cassette because we don't have the huge jump from 26 to 34.
