The chain feels and sounds like it's jumping gears or slipping on the rear sprockets. It does it in all gears. It is a diamondback wildwood large 20"
The rear derailleur needs adjusting, once to establish limits (so it can't go past high gear or low gear). Everything else is up to you fine-adjusting the shifter to make the bike run quietly. If you're careless about your gear changes, you'll get MOSTLY into one gear but not quite perfectly, so the bike is always trying to start shifting into another gear - that's the sound you hear, the sensation you feel. Fine-tune your shifter positions each time you shift - you'll find a "sweet spot" where the bike runs almost perfectly silently.
No, they can't readily do that at the factory, not with chain drives. There are just too many things that can affect gear changes, and things are in a slightly different position every time you remove & replace the rear wheel, or even loosen & retighten it. Unless you're ready to spend vast dollars on a foolproof shifter system, shifting cleanly is going to be your job and your job alone. It's one measure of your bike riding skill... and the better you get at that skill, the better you feel about it.
...and your bike will like you for it.
