No front shock means it's a hybrid IMO. Have you tried emailing the seller to ask for the model number? Looks like it might be printed on the top tube but I can't read it in the lo-res pic. If you can get the model # you can look up specs (including the standover height for that frame size) on Trek's web site.
Would you call this a hybrid, mountain bike, urban bike, what?
Back in the day they made rigid (no-suspension) mountain bikes. Which is what this is. Switch the tires to slicks and you'll have a "hybrid". See how meaningless these marketing terms are sometimes?
As you might guess from my "back in the day" comment, this is an old bike. Its likely a bottom of the line model. I would not pay $200 for it. The current Trek version of the bike (7000 WSD) retails for $360.
