What's with the big sprocket on the left? It isn't attached to anything? If you have a free floating sprocket between two sides of a chain like that will it just turn in place since the top and bottom of the chain are both moving the same speed?

The free-floating sprocket is a quick-fix chain-tensioner.
Tandem unicycles are apparently hard to ride, even for experienced unicyclists.

I can see this going wrong!

Howdy! Bevan answered the question about the floating chain ring. I still need to make a proper chain tensioning mechanism.
FYI, I just posted the building process on my blog:

Something tells me that tire is going to need 60+psi to support two people on one tire.
