Mr. Eric Sir recommends against it.

As everyone who has had a bike stolen knows, there’s really no way to make a bicycle 100% secure – you’re basically balancing an equation where the amount that you spend weighing down your bike with locks only increases the difficulty of the heist. (And according to bicycle law, all bikes should weigh 50 pounds.)

Gizmodo put 4 standard locks through the paces to see just how hard it is to steal a bike secured with a u-lock. Although a few of them fended off a beating from bolt cutters and a hacksaw, not a single one could stand up to a 5-second assault with a $40 angle grinder. Check out the video here – how does your lock fare?
