Someone has been struggling to invent a unicycle from scratch. Calling it a “unibicle”.
The video is a bit long-winded.
So he starts with a bike, then almost makes it into a uni with one pedal and in then end turns it into a bike again, being impossible to ride. He shoulda stuck with the original bike.
That was pretty funny, while being pretty painful. 
Notice his total refusal to utter the word “unicycle”. Because unicycles are hard to ride. Right?
