A "dual suspension bikes" for $200, will be both bad on a trail, and on a road. It will have terrible rims, terrible tires, terrible everything, and will be designed to break near-immediately. All sizzle, no steak.
Walmart could have a bike for the same price with simpler, less flashy features, that was better in everyway. Except it wouldn't pretend to be a capable full squish bike.
IF walmart was to put their heft behind a rock solid single speed it would be be an exceptional win for consumers.
