At the least, before I bought a bike online, there are a few things you need to know....

A womans torso/leg ratio is different from a mans.....you gals tend to have longer legs and shorter torsos than men. This often is pronounced enough that it will affect your bike fit. Woman Specific Designs have a shorter top tube than a guys bike, relative to the same standover. This is a good reason to buy from a shop, especially for a first time purchaser. If your bike doesn't fit, it'll be uncomfortable, and yu will quit riding it.

Of the two bikes, if those are the only two, I'd go with the Worksman, simply because as far as I can tell, Barracuda is out of business, and Amazon is selling off remaining stock. I went to the Barracuda site and they are offline., and there are spam sites parked on their other lead in links now. Not a good sign for warranty service, if you know what I mean.
