if you want my advice; there's 3 categories of bike locks: sham, okay, safe but too much weight

First one is the one you can break open by hand, second one is the one you can't break open by hand and the one you want, third one is sort of safe but also weighs 4kg and feels awful

Until the world changes, my suggestion is to make your bike look shit to the average person but have it be mechanically sound and use an okay lock.
