I need help figuring out how to change a flat back tire on my anura trike---it has a hex shape hole in the middle of the wheel--you know the place where all the spokes come together... i assume you stick a hex shaped thingy in there to unscrew it---I did but it did not budge, not one little iota...is there another way to do it? please help anybody ---I was thinking of removing the fender part so I could at least have working room to get the tube out but betcha dollars to dimes those are only fake screws put there to fool you into thinking they are real.
thanks

p.s. the local bike guy will not call me back and if I take it to Richardson bike mart they will want to keep it for weeks---I would like to have all 3 tires/tubes changed as the tires are slick. there is a slow bike ride in paris I want to be in on Monday.
