Ok, so I dont know if i am just having a dumbass attack, or what, but for the life of me I absolutely cannot get my ergo seat to go in to the tall slot! I have shoved so hard the bike nearly fell off the kick stand! If I pop the back par down, the front just wings out to the side. The bobbins will slide up in to the low setting no problem, but short of a big hammer I am not sure what else to do?! Suggestions?
