Even the bikes sold at real bike stores are pretty raw out of the box--a quality shop will take anywhere from 45 minutes to 2+ hours to get a major-brand bike roadworthy. Shop owners are routinely lied to by sales reps about this--no bike is a 30 minute assembly if you care about your customer's experience on it. No department store assembly should EVER be trusted. If someone doesn't want to pay a bike store to do the assembly, internet and print resources exist to make a bike at least close to non-lethal if not well adjusted.
