U-lock Comparison

Last Updated on August 19, 2022 123 Comments

Here’s a list of some of the most popular U-locks available today. You can use it to compare weights, sizes and security levels. I find the weights a bit hard to imagine so I have also converted them into a handy “number of cans of coke” weight to make it easier! You can also use the search field to filter what’s visible. For example, if you only want to see Sold Secure Gold rated locks, enter “Gold” into the search.

There is a similar table that compares chain locks here. If you’re still unsure about what type of lock you need, check out my lock guide. And if you need more specific recommendations have a read of our U-lock buying guide.

Most of the information in this table comes from the websites of the brands themselves. However, the weights of the OnGuard locks are not provided on their website, so I had to hunt around a bit and they may not be 100% accurate. If you see any mistakes please let me know and I will correct them!

Any data that needs further explanation is annotated with * and further details are provided at the foot of the table.

I hope you find the table useful. I’ll be adding more locks as I find them and if you have any locks you would like added please let me know below.

And if you do find it useful please share…

About the author 

Carl Ellis

I've had bikes stolen in London, New York and Barcelona. Yep, I was a serial, international, bike theft victim. In 2015 I decided to stop the rot. And not a single bike's been stolen since! Brakes, yes. Bells, yes. But they're another story. Everything I learn, I document on this website. More about my story. Contact me. LinkedIn.

  • I want to thank you for creating this highly useful and one-of-a-kind resource. There are more options that suit my needs than I previously thought!

  • A great list and a great help! But I have to notice a continuing error: Master Lock 8195 is NOT 16 mm thick, but only 13 mm.

    Btw, I have a Master Lock 8195 for a couple of months, and so far I’m very satisfied! (Although, I’m still trying to find out: what makes it Sold Secure Gold if for example OnGuard Pitbull is only Silver?)

  • Hi Carl,

    I compliment you on your educational, and very informative articles.
    What are your thoughts on the Tracki Real-Time Worldwide GPS Tracker? A subscription is required monthly or annually depending upon one’s needs. There is a magnetic waterproof box and power pack that is offered to extend battery life from 1-6 months depending on usage.
    Also, Hiplok just came out with their D1000 Anti-angle grinder U-lock. It’s expensive…$300+…..your thoughts?
    Regards,
    Ron

    • Hi Ron,

      I hadn’t seen the Tacki before. It looks promising. Have you tried it?

      As for the Hiplok D1000: it will be the only angle grinder proof lock available when it becomes widely available, so they can charge whatever they like!

      Bearing in mind that the Kryptonite Fahgettaboudit Mini is around $100 and despite being the most secure portable lock in the world, it can still be cut by an angle grinder in less than a minute, then perhaps $300 for a lock that can’t be cut by an angle grinder in any reasonable time, could be seen as a bargain!

      Thanks

      Carl
