Have never had to do that as I am a short 6'1".
Don't think that you will find a bike to get you up a 30% grade. 20% is very steep.
Not to mention a hill with an angle of 30 degrees! That sucker would have a grade of approximately 58%. (The grade is the slope (i.e., the tangent of the angle) converted to a percentage, so in particular, a hill that rises a vertical foot for every horizontal foot (angle of 45 degrees) has grade 100%.)
