I have some rides logged on Strava and garminconnect if you want the GPX files, but to be honest you are better off going out on a group ride as most of the trails are easily missed and local knowledge is king.
Änggården is a good place for exploring without getting lost and has some really good technical steep descents.
If you’re after long groomed trails then you’re in the wrong place unfortunately. To find them in Sweden you need to head north to Åre, Järvso and the other bike parks, but they are so far away it’s quicker to get a flight to the Alps, Scotland or England (Åre is a 12 hour overnight sleeper train).
My advice would be to adapt to the terrain and riding here. It has definitely improved my technical riding living here and most people ride 140-160mm bikes (is that AM now?), so you’re not out of place.
If you’re keen on a ride Tues evening I can show you around some of the trails I know.
