Two of the toughest locks on the market with certifications to prove it. These locks are about as heavy-duty as it gets, with some optionality between them based on how much weight you want to carry.

Bike theft stats are the kind of data I don’t enjoy digging into. The last national tally reported roughly 150,000 bikes stolen in the U.S. in one year, totaling around $148 million in losses, but that’s only what gets reported. Some studies into the matter estimate the real number of stolen bikes is several times higher. It’s a bleak reminder that a good lock isn’t optional; it’s the barrier between you and becoming part of an unfortunate statistic.
The Litelok X1 and X3 are true heavyweights amongst bike lock options. These two have developed a reputation for doing what few locks can: standing up to angle grinders, which is the go-to tool most modern thieves rely on. Both models carry Sold Secure’s top-tier Cycle Diamond rating, earned through independent, destructive testing by the Master Locksmiths Association in the UK. They’ve racked up awards, industry buzz, and plenty of real-world validation. After spending time with them, I’d say that praise is well deserved.
“Anti–angle grinder” is a bold claim for any lock, and it’s important to be realistic. No product is unbreakable. But the X-series Liteloks dramatically raise the level of effort, noise, and time required to make a cut. According to Litelok’s testing, the X1 stands up to grinder attacks about five times longer than leading U-locks, while the larger, heavier X3 pushes that to around twenty times, thanks to additional layers of their proprietary Barronium® composite.
Both locks check the boxes you want for solid security: tough to cut, soft outside to spare your bike’s frame, and they have attachments to secure it to your bike to bring it along easily.
We’ve been pretty happy with using them daily, haven’t lost a locked-up bike yet, and other than a little heft to the lock itself, it seems virtually downside-free if it’s within your budget.
