## Description

desertcart.com : SIGTUNA Folding Bike Lock - Hardened Steel 8mm Fold-Up Heavy Duty Bike Lock with Easy Mounting, Secure Lock and Anti-Scratch Coating - Easily Keep Bike Secure and Paintwork Undamaged - Bicycle Lock : Sports & Outdoors

Review: Compact Security Without the Bulk of a U-Lock – Great for Everyday Stops - Compact Security Without the Bulk of a U-Lock – Great for Everyday Stops As someone who bikes regularly (including quick errands and beach runs), I’ve been looking for something more secure than a basic cable lock but less bulky than a traditional heavy U-lock. This SIGTUNA folding lock hits that sweet spot really well. First impression: it feels solid. The hardened 8mm steel bars have real heft to them, and once unfolded, it wraps comfortably around a bike frame and a fixed object like a rack or post. It doesn’t feel flimsy or toy-like at all. At the same time, it’s not excessively heavy. It’s noticeable, but reasonable for the level of protection it offers. What I like most: – Compact when folded. It tucks neatly into the included mounting bracket and sits cleanly on the frame without looking awkward. – No rattling. Once mounted properly, it stays put during rides. – Flexible locking positions. Compared to a rigid U-lock, this gives you more options when locking up to odd-shaped racks or thicker posts. – Protective coating. The anti-scratch plastic coating is a big plus. I’m careful about my bike’s paint, and this doesn’t feel like it’s going to chip or scuff the frame. – Smooth key operation. The locking mechanism on mine works cleanly—no sticking or forcing the key. Installation was straightforward for me, but I can see how some people might get tripped up if the included tool doesn’t match perfectly. If you have a small Allen wrench set at home, that makes things easier. A couple things to keep in mind: – This is not a “leave your bike overnight in a high-theft area” lock. It’s strong for everyday use and clearly better than a thin cable, but determined thieves with power tools are always a different story. – It’s heavier than a minimalist cable lock. If you’re an ultralight road cyclist obsessed with shaving grams, you’ll feel it. For commuters, hybrids, e-bikes, or casual riders, it’s a very fair trade-off. – Make sure you mount it securely and test it before your first ride to avoid bracket movement. For quick stops at a coffee shop, grocery run, or locking up at work in a visible area, I feel confident using this. It provides real deterrence without turning my bike into a weightlifting exercise. Bottom line: A well-designed, compact folding lock that offers meaningful security for everyday riding. Not indestructible (nothing is), but a smart, practical upgrade over basic cable locks. Definitely a 5-star value for the price.
Review: Me Like - Thieves Hate - 2 Bad 4 Dem ( - I first saw this lock design during my European travels. Amsterdam, Belgium, Holland all have larger bicycle riding populations which rival anywhere in the U.S. We had a couple bikes stolen from the storage rack at the Florida condo and I decided to try these to keep them safe from the dirty, rotten scoundrels who prowl for other folk's hard-earned stuff. These have a nice bike mount "holster", so they transport comfortable attached to your bike and are rugged anti-theft devices! I've owned them a few years now and they have held up nicely, even in the salt air environment here on Siesta Key. Definitely worth the investment, every penny and I highly recommend this brand.

## Questions & Answers

**Q: How compact is the folding lock?**
A: I have mine attached to the seat tube. It is no bigger than a water bottle.

**Q: Could you please measure & post how many mm thick the metal plates are?  thanks!!**
A: The metal plates are 7.5mm including the coating on the metal plates.

**Q: How can I get a new key in case my keys get lost or stolen?**
A: You have to contact the company.

**Q: I ordered this lock and it was all black with no yellow, is there any differences between the two besides color?**
A: Hi Matthew, Thanks for the feedback. No, there is no difference. It is the same model Folding Lock, but just with a different color. This is due to a packaging error that could not be corrected earlier. We hope this is a too big of a problem. Please contact us at customers (at) sigtunagear.com if you want to give us feedback.

### ⭐⭐⭐⭐ Cool, lightweight lock but incorrect mounting tools
*by M***L on September 1, 2025*

This is a very clever, lightweight bike lock, and seems like it will be quite secure. The reason I'm giving 4 stars instead of 5 is because the instructions and tools provided for installing the bracket were insufficient. I purchased the "new" model; I suspect that the instructions and the Allen wrench were meant for the previous model, as the Allen wrench was too big for the screws, and the instruction to "place washer on bracket" made no sense. Once I found the correct wrench in my toolbox and figured out how to position the washer, though, installation was easy.
