My colleague bought a Sem XL a few weeks ago because he decided that unicycling was going to be his way of keeping fit instead of running. I suggested that he start getting the feel for the uni by supporting himself in a doorway and just rocking back and forth. He has taken this method forwards, so to speak, yup, he is now starting do go a few pedal revolutions through his condo.
This afternoon he greeted me excitedly at work and said, hey I’m doing great on the uni… I’m deep into the living room now!
