I'm surprised i've read so much about locking bikes but I haven't seen anyone mention how important it is to lock your bike as high as possible. What I mean by that is have the lock up on the bike as high as possible, the higher the lock, the harder it will be to use bolt cutters on them. Like in the videos shared, the thief would put one arm of the cutter on the ground while putting all their weight on the other arm, much harder if not impossible to do if the lock is up high.
