The 8 Best Hardened Steel Bike Locks (2023 reviews)

The Sigtuna lock is a viable and cost effective alternative to pricier ( and better designed) bike locks. It is a very heavy-duty lock, plus a stout cable. The lock itself is built well and the mechanism feels far more solid than the kryptonite or onguard. It is coated to not scratch your frame, it is heavy-duty, and it comes with multiple keys. The cable is long enough to secure the front tire, while wrapping around a sturdy pole or rack.

This lock works as well with motorized bicycles, scooters and motors. The lock is sturdy, featuring a thick locking bar and a secure latch with virtually no play. Will definitely keep your bike secure and the imposing look of the lock will deter any potential bike thief.

This lock is WAY easy to cut if you consider using it to secure the whole bike. The Vinyl cable coating protects and resists rust. The plastic liner on the cable makes it easy to handle without cuts from the metal cable. The U-style can go on either end, more flexible from others where one end is curled slightly, and the locking bar only goes on one way.

These locks are built with double locking shackles and high-security disc cylinders. The lock comes with 2 keys, made for that specific lock. The literature/packaging has instructions on how Master Lock recommends you lock your bike. It is great for college students because of it's convenience and durability.
