The idea sounds nice but it is not possible to balance/steer a bike
without a pivot. You keep you're balance on a bike by constantly
falling left/right and correcting this.
You correct the falling by steering, lets say you "fall" to the left.
At that moment you will steer also (a little bit) to the left and the
bike gets back under you, and you can start falling again ;)
With steering it's even more strange you first steer (a little bit)
the bike in the opposite direction, this makes you "fall" in the good
direction and you can make a turn till you get the bike straight.
