The only racks I know of that would go on that bike would cost nearly as much as the whole bike, lol.

It's hard to put a rack on a full suspension bike. Also, the stereotype on the forum is that when buying a $120 bike like that one the full suspension is crap, and it's better to buy front suspension only, at best.

You mention a rack, panniers, but your link is to a kids bike - are you trying to bring your kid touring? If so I would also suggest no suspension or front suspension only, as rear suspension is going to make the kid even slower on the road. Cheap rear suspension (even like the kind I have on my bike) really hurts your efficiency (and I mean that in a "a normal person will notice after riding the bike for a while with someone who's riding a non-suspension mountain bike" kind of way.
