HI! I have the same problem. II have been riding for almost 3 years now. And sidehops were the hardest thing to do. Once I nailed the technique I was going higher every week. But the I stoped at round 80 +- 10cm. Coud not do anything higher for months! And like you we have not got lot of riders here, so I learn prety much by watching videos. All of the videos I watched, before the sidehope, riders find they balance point then preload - while preloading, your body and the front well can go quite low, then shoot up as fast as you can. Horndean Trials explained it quite well. Since I nailed the balance point I can now do 105 max. This is where I am stuck at the moment, I think I just need more power But the best way to pull your back wheel is the sidehop landing to front wheel, pushing it down and bringing the back wheel up by a little pivot. But that only works on the obstacles! Hope it helped.
