Good reviews here. People using it for very long distance touring and commuting. Changing the gears for mountain climbing.
Lots and lots of bike reviews. List many cycles and why they are good or good at their job.
The consensus seem to be that this a good value. Everyone recommends waiting till REI puts it on sale for 15-20% off.
Not a lot of choice in Amarillo. REI has real stores, but sells through the internet.
My current Walmart bike is great for training. Very heavy, lots of suspension, wide tires. If I can just find a 26″ X 1.5″ front wheel with quick release. That way it fits in the trunk without a big fight.
