It's balancing in place on a bike. You turn the handlebars 45 degrees one way or the other, and find the balance point. Since the front wheel is turned, when you pedal forward you lean one way, and when you pedal backward you lean the other way. It's sometimes employed in track cycling (where fixed gear bicycles are used), hence 'track stand'.
