The impact huller can be powered with different motors.  I was unable to create a method of powering the impact huller with a bike.  One may need to create a 30 inch pulley which would be quite difficult to obtain 3,000 rpm. This video  has building instructions.

This video is of the impact huller directly attached to an electric motor
