Just keep in mind that unless you are going to charge only while the sun is shining, you will need a very large battery. 12v 36ah will barely be enough so you would want about twice that and in deep cycle form, not a car battery. Another thing to consider is this, 36v at 12amps is 432 watts. Your panel is 60watts so on a very good day, you will probably get 240-300watts That means that realisticly,you would have to plan on taking 2-3 days to charge the bike from fully drained.
