I personally wouldn't have any concerns about the bike, except, as stated, the wheels.

Not only is the extremely low spoke count an issue, but look at how tight each position has 2 spokes. By putting those two spokes so close together, there is less metal around each spoke and I would be truly concerned about them cracking. My wife has that design, albeit with a higher spoke count, and I fully plan on replacing her wheels sooner than later.

IF THE BIKE FITS (most important aspect of buying a bike), then I'd buy it, sell the wheels and use that money to put toward new wheels. You could spend $300 for a decent set, $600 for a very nice set, or anywhere above that for awesome.
