Double-decker tandem: How would the stoker climb aboard? Severe balance issues, as well as stability issues when braking or climbing. A double-decker would be extremely dangerous to ride!
The half-recumbent tandem is a Taiwanese version of the venerable Bilenky Viewpoint tandem, which is itself base on the older Opus III Counterpoint tandem.
