Just my opinion but 3000w is going to destroy a Walmart bike in no time. It's also going to be scary to ride because the geometry is most likely rubbish. When I got my first proper bike it was absolutely amazing to ride and most of that was down to precision of the components and geometry. Cheap bikes deliberately have poor geometry to make you buy the more expensive models.
I had a $1500 Trek that only lasted ~12 months of commuting and that's just with pedal power.
Should be fun while it lasts though
