there is enough footage on you tube and here to learn from,you got to have a posative mental attitude to,my step son is in the same position he is just starting and i been able to hop about for years and it is so difficult to explain,the best thing you can do is practice practice practice and then once your done doing that practice some more. id recomend varying it though try front hops too,track stands,bunny hops and hoping on both wheels up kurbs that way you wont get bored of just trying back hops
