Personally I don't see why not. But that would bepend on your gas supplier, the bottle stamp/certification, and maybe a few things that I am not aware of... (laws/regulations on those peices.) Putting that asside for a second... does it have a regulator? If not you may have to get one. They come in either an adjustable version or a fixed output version. As far as questions on the bottle and rather or not you can use it for that... if in your shoes, I would take it to the place I would have it filled at and ask them.
Skinny Pedal I think has some good deals on some kits.
I have asked my guy before about filling mine with nitrous before and he told me that with the bottle I have (like Skinny sells) it isn't a big deal as long as the regulator could handle it. There have been in the past several different threads on here about CO2 and nitrous and different setups. Might check them out if your thinking of buying a setup.
