I just recieved a Walmart bike from my folks. It's a CCM. Apparently it normally costs $200, but was on sale for $100. I am just wondering if anyone knows what the quality of this one is.

I was feeling very depressed as a result of recieving it, but now, from what you guys are saying, I feel like there is hope.

2 major questions I have:
-What are the first parts to typically fail?
-How durable is the frame? Because if the frame is good, then upgrading stuff should be no problem (ideally, I'd like to get a 3 or 4, maybe 7 speed internal shifting hub... someday... and probably slightly thinner tires).
