I like to bike when I can, but I’m still nervous to leave it even with a U-lock around the frame. I’ve also had a seat stolen before (not even a good one), but I’m not sure if there’s anything reasonable to do about that.
What do you do to lock up your bike for commuting?

Hexlox for the seat, seatpost suspension, and handlebar bolts, as well as hexlox for the axles.
Abus granit x-plus u-lock, cafe lock with Abus chain lock integrated, and a cable lock for my front wheel.
Also bike insurance.
I have all these stupid locks because I have an ebike. I have an ebike to help offset all the weight of these stupid locks.
