Bergamont
 

Hello! I purchased what I now realize is a fairly rare bicycle. It's a Bergamont Vagonda special edition. It's a German made bicycle and I haven't been able to find one for sale in the US. Does anyone know what it might be worth? Would it be worth more because there aren't any dealers in this country?

Probably worth about what you paid for it or a little less. Until you find someone that wants to buy it, it's only worth something to you.

What's this country?

Probably worth less here in the USA because no one knows anything about them.

Value is only determined by what a willing buyer will pay.

It's funny that the company website has a model archive but if you enter the model you named it does not exist. https://bergamontfb.de/archiv/index.php

From what I have seen it looks like a pretty generic hybrid with lower end parts from Europe. You get some interesting hydraulic rim brakes from Magura and a dynamo system but overall not worth a ton they sell on some euro sites for under $600.

It's a low-mid range touring-city bike. It's only rare in the US. I do not see why it would be worth more than other brands, it does not have anything particular about it.
However, if you want to ride it, it seems like a capable bike

It's rare because they don't sell bikes in the US (I am assuming that is where you are). In Germany, they are commonly sighted in towns and cities, because their target demo are urban users who are using bikes as an alternate to their cars and public transit, as well as on the millions of miles of bike trails and paths, typically under older people who are having a Sunday drive at 10-15km/h zum nächsten Biergarten für ein Radlermaß und Würstchen. They are "valuable" in the sense that they give the user options, and left unlocked provide a thief a quick, though joyless ride for a few hours until they dump it. Other than that, they are boring bikes.

Nur ein Radlermaß?

Es ist genug, wenn ich auf dem Fahrrad bin.
