The Ozark Trail does look like a lot of bike for the money, that said, I'd still be wary for a few reasons. Being sold by Wal-Mart, you would be getting a bike quickly slapped together by someone who may or may not have any idea what they are doing. Proper installation and adjustment of everything on the bike plays a big role in how well everything works, and how long the parts on it last. Chances are, even if the person slapping it together does have an idea of what they are doing, they won't have the skills to identify any issues with the frame, whether it be alignment issues, disc tabs not properly faced, one dropout sitting higher than the other, etc. A bike built at a real bike shop will be noticed if such issues are going on, and will either be fixed, or set aside for warranty before it would have reached the sales floor.

Wal-Mart bikes and cheap ebikes often have poorly built wheels. If you want something that will hold up to touring, I'd expect to replace at least the rear wheel on the Ozark Trail, or have the rear hub relaced into a new wheel on the Mokwheel. Doing so would drive the price closer to what a higher quality bike would have cost in the first place.

Since you plan on touring, I'd figure out what kind of handlebar setup you want before picking out a bike. Drop bars offer multiple hand positions so you can change things up as you ride, helping with comfort over longer distances. Some people can't really handle the more leaned forward position drop bars put you in (Including me), and it would be wise to figure out if they are even what you want before buying a bike. Go test ride some bikes, figure out what works with your body, then decide what you wanna get. Consider using the money you would have spent on an extra battery to instead go towards a higher quality bike up front.
