A question about bike thefts in Oslo

Hi all!

I am relocating to the Oslo area soon and I will be bringing an expensive electric bicycle with me, at least by my standards. What is considered an expensive electric bicycle in Norway? Where I come from, it's never parked outside, and when it's left unattended on the street even for just one minute, it's always properly locked.

I was wondering how secure it is to leave an electric bicycle unattended around Oslo. Are bike thefts common? I am concerned that I might find an apartment without a garage or any place to store it, and my only option might be to store it in a dedicated common space for the entire apartment complex.

Thank you for your kind answers!
