Rite when you approch the wall make sure you are at a 45(ish) digree angle to the wall. Do a small hop to build some momentum then pull up as high as you can then place the front wheel on the wal and swing your rear wheel up on. And there you go you can side hop. I know it is not a good description but if you use the search you will probably find some other topics about this, they may be more helpful. Adam.
