FWIW, I entered "Fuji Nevada 4.0" into Google and got pages of information. For value guesstimate, the current model sells for $450-$550.
Good luck with your new bike.

$100 plus $35 for the hitch. Holds a mere 50 lbs, but folds and is light and simple. When decoupled works like a hand truck which is very cool; even stands upright. Got one for my wife, but haven't tried it yet except around the driveway, and if felt great, even when overload with a huge rock. I did have to make a custom hitch post on the bike in order to clear her Tubus rack, but if you have shorter rack or different bike geometry that won't be a problem for you. Besides making the hitch was a fun project.
