That does sound like an interesting bike - do you konw of any links to pictures, descriptions, etc.???
It's built using two bikes fitted together side by side with a special kit comprised of bars, cables and turnbuckles to keep things tight. The front handlebars steer in tandem via a tie rod and a piece mounted to each stem. It's far more comfortable than a standard bike, and much safer too. A slightly used demo model cost me $300 more than the 300SD! Kevin in Hillsboro, OR
