Why is my bike SO slow?!

i still say, get rid of the stupid bike. You won't be sorry. Or you can take it to a shop and have them try and find what was wrong with it.

I have to agree with Mimi. If you had a lot invested in it and/or it was a fine bike, then it would certainly be worth trying to figure out what is wrong. But as inexpensive as it was, I'd just try to sell it for ~$300, figure the $50 was not a lot to lose, and move on.
