Best Abus Bike Chain Locks in 2026

The heavy, rhythmic clinking of these 5/16-inch thick steel links is the first thing you notice, signaling immediate industrial-grade strength. Unlike standard round chains that allow bolt cutters to slide easily along the surface, the ABUS square link design creates an awkward geometry that makes it nearly impossible for theft tools to get a secure grip. I was particularly impressed by the thoughtful inclusion of a nylon sleeve, which prevents the hardened steel from marring the paint on your motorcycle or ATV. It feels incredibly substantial, requiring six tons of force to compromise, and the anti-corrosion coating ensures it won't degrade when left out in the elements. Whether you are securing a residential gate or a commercial trailer, this chain offers a level of physical deterrence that feels genuinely insurmountable.

You are leaning your bike against a lamp post in a busy downtown area, feeling a momentary sense of relief knowing your gear is actually secured.

I found the 85cm length to be a sweet spot for most standard bike frames, offering enough reach to loop through the wheel and frame without being a massive, heavy burden to carry. One detail that really sets this apart is the pinned fabric sleeve. It wraps the metal tightly so you aren't constantly worrying about the chain scratching up your bike's expensive paint job. It even comes with two keys, which is a small but vital convenience for any owner.

Most people assume a thicker shackle is the only way to stop a thief, but the real battle is actually fought against the cylinder. The ABUS 20/70 Diskus flips the script by using a specialized disc cylinder that makes drilling and pulling incredibly difficult.

I found the build quality to be exceptionally robust, which makes sense given that ABUS has been innovating in security since 1924. It is a heavy-duty solution that prioritizes manipulation resistance, making it a standout choice for anyone who needs more than just a basic padlock for their valuables.

Most cyclists assume a chain lock is just a heavy piece of metal, but the Seatylock Viking changes that skeptical mindset with its clever engineering.

It is built for the elements, featuring a UV-protected neoprene sleeve that prevents frame scratches and a silicone polymer coating to fight off rust.
