Yep, all you can do is harden the target.
Also, you can buy for cheap Air Tags, which are about 1” diameter, magnetic, and you can hide it anywhere on your bikes. If the bike is stolen, you can track it’s location quickly, call the cops and meet them where the bike has been tracked to. Cheap meaning about $20-$30 bucks for 2 tags.
I use them on my motorcycles..
My daughter and SIL have those their bikes.
I always wonder if thieves have been able to get around the frame lock— it’s a spiral lock and I struggle with it - also the console. How could they get another one?
Can the air tag tell you top speed reached? That would be a cool feature to have.
