Hello All -

I bought a Schwinn Ranger from Target that was pre-assembled. It seems like it'll be a good fit for me, but the shifter doesn't seem to be working properly. It has I think 21 gears, but no matter which gear I have it in, it makes that noise like it's going to shift, which I've gathered is not a good thing. I'm not really a bike guru and I just want to ride it, but is there some way I can fix it? Thanks for any help.
