Infinite Tandem Bicycle

I had a dream about a tandem bicycle that two people would only be able to ride in zero gravity. When I woke up I realized how ridiculous and impossible that would be, and I was interested in exploring the idea further. I was calling it the Impossible Tandem Bicycle until my father-in-law gave me a book called The Infinite Book by John D. Barrow. After reading it I noticed many of the patterns in the bicycle drawing create infinity signs, so I changed the name to The Infinite Tandem Bicycle.
