I can't really tell from the photo. You are the only one who can answer your question though. There are four things that you really need to answer to see if it was a good deal.
First: does it fit you? Riding a bike that is the wrong size can become sheer torture, in which case the bike is worthless.
Second: are you happy with it? If you are not happy riding it, then once again, it is worthless.
Third: is the saddle comfortable? If not, a new saddle can cost anywhere from half the price of the bike to more than triple the price of the bike.
Fourth: are you a competent bike mechanic? If not, you will probably have to get this bike tuned up at your LBS, usually around $120.00 which means that your $80.00 bike is now a $200.00 bike.
