I'm gonna guess it has pinch bolts, so loosen the pinch bolts first (ones on top of the crank arm), then tighten the middle bolt, then tighten the pinch bolts again

im talking bout like the inside of the crank the arms are tight but you can wiggle the middle in and out

have you taken them off before?

maybe you need a spacer that isn't on there...

first one needs more spacers, second one the BB needs tightened. best to take that one to a shop cause it's easy to fuck it up if you don't know what you're doing

o and one last ? do these bikes use a one eigth chain or a three thirty seconds sorry for the noob questions

Yes, and should be able to but if not, then I'm sure they have a bottom bracket you can buy that comes with the correct spacers. And it's usually 1/8"
