U-lock Comparison

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…
