Would Wal-Mart be an ok place to buy one?
I don't want to end up getting a crappy bike where the brakes break within a couple months or something.
no. go to reputable bike shop, get sized, figure out what feels comfortable in terms of style, road, cross, mountain, single speed etc..then buy the most expensive helmet they sell and look for the bike you chose on craigslist.
