I cant do a manual. I cant pull the bike up high enough. It seems like when i pull the bars up wards, the pressure of my legs on the pedals always forces the bike back down. I can do a wheelie on the back pegs cuz theres no pressure on the frame. Ur just standin to the center of the back wheels. I can only pull it up like 1.5 ft when on the pedals. Are u supposed to jump up or something? Or is my bike too long for me. I ride a pro sized bike and im 5ft somethin. I noe this has probably been asked before so i'm tryin to be more specific.
