It depends on what your wife is looking for. If she wants a lightweight entry level track fixie then she should go with the Kilo TT, the SE premium brew and powder coat over the butt-ugly paint job, or a bike from state bicycle co. Of those three, the state bike will be the lowest end, due to its crappy components. If quality is the most important factor, the Kilo TT would be ideal. If she wants a freewheel city bike, then she would want to go with something like a Fuji declaration, a Jamis Sputnik, or a State Bicycles shoreline or domingo. If its a cruiser she wants, then some ideals would be something along the lines of an Electra. The Schwinn lakeshore is also a very good option, although you would have to take the gears off, which would be relatively easy.
Hope I helped!
