Hi you Firstly you want to get good at hopping on the back wheel. This is a more controlled method than doing one hop. So you start hopping next to the obstacle you want to sidehop. Once you feel good and think your in the right postion you pause on the backwheeel. Then hop again but as your wheel comes down preload. This means you put your weight back and lower the front. Then at the same time kick the pedals and jump up. Now you want to bring the handlebars in towards you then push them out. While doing this you want to bring your knees up and push the bike onto the wall. With any luck you should have made it and you can then start practising and getting big. Another tip is to aim the front wheel onto the wall so if you back wheel doesn't make it you will go to pedal and not to face. Sorry if its hard to understand because it was rushed a bit. Hope it helps and also try and look at trashzen. Matt
