>>2006429strong heat treated chain is the best way to lock your bike, make sure to also lock your front wheel and you should be fine. U style locks are also good but you cant attach it to your frame so you might come back to a wheel with no bike.
bike thieves don't normally use an angle grinder unless you lock your bike in an isolated area with no witnesses, 90% of the time its bolt cutters because they can just SNAP and go.
i used to lock my mountain bike outside of my apartment complex, that place is full of shitheads and one day i didnt lock my front wheel so the next day i had to buy a new one because it was gone. i also stored my shittier bicycle in my shed just to find it gone one day so i had to install a U bolt to the wall and chain it that way. sucks for me that i didnt have a lock in that shed's door
>If a thief with an angle grinder sees it and they want it they will take it. Nothing can stop them. Therefore in my opinion it's best to reduce the chance they will see it in the first place. CCTV and crowds don't deter anyone anymore. I've seen many videos of bicycles being stolen on a busy street in broad daylight.large population cities are honestly the best place to lock your bike, with an cordless angle grinder and sturdy lock its going to take 1 minute or more to get through if you need to cut in several places, with bolt cutters and trash lock its less than 5 seconds. the chance of a cop seeing it and reacting appropietly or someone calling the cops is waaay higher than in a residential street where someone might peek through a window and figure its just some dude who forgot his key. covering your bike might attract more attention to it due to curiosity instinct, i honestly would peek underneath the cover too without intention of stealing it.
nonetheless even if you are insanely paranoid about bike thieves, a thief might follow you home and just note down who you are and where you live and wait for an appropiate moment to get inside.
