I got the bike for free so it’s not like I’m protecting an investment, but y’know I don’t wanna replace it, having it stolen would suck. They all seem hella expensive, I was thinking of just going to the hardware shop and buying a fucking big chain and padlock lol.
Most of having a bike lock is having a better one than the bike next to yours. So don't get a cheap wire one, or a thin chain or a combo lock. I have an Abus one which I like a lot, and has marks from when someone tried to cut through it with a pair of bolt cutters.
