It does look short to me for a tall rider. If it doesn't fit you comfortably don't put money into it. Make sure your ride fits you whatever you choose. You should be able to extend your leg just short of being straight with the pedal down. You wouldn't like long rides on a bike too short for you I can say by my own experience.

But if it does fit, replace the tires and tubes. Don't forget to carry pump (or C02) spare tube, patches and tire spoons when you ride.
