What a great bike to start on! I have the Trek Navigator 2.0 My DH got it for me a year and a half ago as I wanted to start riding. I did know how to ride a bike, though it had been years. Now, I have 3 bikes total, and have done 2 triathlons so far this summer, and a part time job as a group ride leader at my LBS. It's addicting, in a great way!
Welcome and happy riding!
