I just wanted to update that I ordered the bike from the website (believe it or not, I actually hate Walmart and don't want to step foot in it if I can avoid it!) I had tried it out in the store already and liked it.

I will have my neighbor help me assemble it and teach me about it, and buy the books recommended (or at least borrow them). I will replace the pedals as well.

I REALLY appreciate the tremendous response I've gotten here. I've read all the replies- please don't feel like I just ignored you if you told me not to get the bike... I just weighed everything I was hearing and decided to give it a shot. I seriously considered getting a used bike, but don't have the time or confidence to go that route right now.

In the future, if I end up biking a lot, I'm sure I'll upgrade to a "real" bike (you know, not a "toy") and will come back here for advice, because really you have been a GREAT resource!

Thank you!!!
