Ha! Have you actually ridden these? I have, and a fully rigid bike-shop MTB is far superior to their junk suspension. Some of those bikes weigh over 40lbs.
By the time you get done upgrading the crap that doesn't work on a BSO, it will have cost you more than a lower-end bike shop bike. And you'll still have an incredibly heavy BSO that isn't fun to ride.
