What is it called when you ride around on your back wheel?
Balancing on your back wheel (with the front wheel in the air) while pedaling is called a catwalk.

(Sorry about the wikihow link, it was the only source I found other than youtube)

Edit: It seems the wikihow link is dead. As far as I can tell a manual is leaning back and raising the tire but not pedaling. I found a couple of other links that make reference to it being called a catwalk:

  Not a Wheelie.  Its a Cat Walk.  A Wheelie you stay seated and ride on your back tire.  If I am correct you actually stand up and pedal up and keep pedaling, which is a Cat Walk.

It's very possible that catwalk is a regional term.
