bbb sells top of the line(expensive) bikes which you dont need. walmart bikes if they are assembled correctly are ok but will break down too soon. i suggest you buy a used one on craigslist or see if bbb has a nice used model. keep in mind you will need a helmet, bike lock and reflector/bike lights. a cheaper but moderately maintained bike will last many years. air in the tires and oil on the chain will go a long way. brake lines need to be tightened every once in a while. there is a fellow who advertises in the masah matan called "the bike man" who does excellent maintenance.
