I bought my bike used and I love it, but I'm not sure what the specific model is so it's hard to buy upgrades for it.
All I know is it's a Schwinn and it says "bomb-proof" on the front fork.
If you can help me out, it's greatly appreciated. :]
It also says "Frontier" on the frame, but after looking at pictures on Google, that doesn't seem right, unless there are a variety of Frontier bikes.
