I stripped a bolt on my bike

i stripped one of the back bolts on my bike, i think its rusted on... The bolt is almost a perfect circle. anyone know how to take it off?

pneumatic air rachet attached to an air compressor

Tried Vise grips?

isnt there a way to get the rust off? i forget the formula...something with lemons and vinegars, will that help?

Yup vise grips and a good liquid penetrant like WD-40.

Liquid wrench or brake fluid will do much better at penetrating and unfreezing it than WD40. As for removing rust, coke does a damn good job. Toothpaste does decent as well. And, if you have to get the bolt back into grabbable condition, get a file and file two opposite sides flat, and use vise grips.
BTW, is this "bike" a bike like motorcycle, or bicycle? (I speak from experience about removing rusted bolts/screws/rust because I have owned 2 20 yr. old motorcycles)

If you don't have a vise grip I would imagine you don't have an impact either. If you did you could just put that bad boy on their and shake that biotch loose 😉

We had to use one of them to screw apart the clutch on my snowmobile damn them things are on there tight.

vise grips and liquid wrench.... make sure you are not trying to turn a reverse thread bolt. Are you talking bicycle? There are 2 reverse thread bolts/nuts that I know of; one of the pedal attaches reverse thread and one crank arm is reverse thread.

If you do use DD's suggestion of using brake fluid instead of wd 40, PB Blaster, or another penetrating lubricant, dont let it contact paint too long or before you know it there will be no paint left. I agree try vise grips. Failing that I would use a torch and heat it until the bolt is cherry red and try again. If that doesn't work or you can't get it pay $10 and take it to a machine shop in your area and let them go to the trouble 😉

Try PB Blaster and vise grips.
Also wintergreen makes a great penetrating oil.
And as someone suggested, makes sure you know if its left are right-handed threads.
