My tip,as I've recently regained my confidence on manuals.First of all,to get the front hweel up,compress down on to the bars,then in one smooth fast motionstart to pull back. I find you should pull from the shoulders,by leaning back,and try and bring them down and back. Your arms should be straight,they're only there to attach u to the bike, you don't physically pull with them as such,the pulling comes from leaning back and dropping the shoulders. Something that helps me to get the front whele up is too straighten me legs at the asme time as I lean back, and pushing the pedals forward with my heels kind of. Once you feel the bike start to reach the balance point,bend your knees,that should hopefully bring the bike under control.
My 2 pence!
