Step 1: Choose the mounting location Decide where on your bike you want to mount the U-lock bracket. Typically, the most common locations are the seat post, the top tube, or the down tube. Choose a spot that is easily accessible but also doesn't interfere with your riding. Step 2: Attach the bracket to the bike Once you have decided on the location, use the provided screws and a screwdriver to attach the bracket to the bike frame. Make sure the bracket is securely attached and tightened so it doesn't move or slide around while you're riding. Step 3: Test the fit Before you put your U-lock into the bracket, test the fit to ensure it will hold your lock securely. Insert the U-lock into the bracket and check to see if it fits snugly. If the fit is too loose or too tight, adjust the bracket as necessary. Step 4: Secure the U-lock in the bracket Once you have ensured a good fit, place the U-lock into the bracket and make sure it is secure. You may want to give it a little shake or tug to ensure it won't fall out while you're riding. Congratulations, your U-lock bracket is now installed! How to lock the bike lock -Q: Why isn't the key turning when I try to lock or unlock the U-lock? A: The key may not turn if the deadbolts aren’t fully inserted. Ensure both deadbolts are completely engaged with the lock before turning the key to prevent any obstruction and ensure proper operation. -Q: My U-lock isn’t closing properly, what should I do? A: The rubber cover may have shifted, causing the lock to not close fully. Adjust the rubber cover back into place to ensure the lock fits correctly and the deadbolts can insert as intended. -Q: How can I ensure the lock works every time? A: Always check that the rubber cover is properly aligned and both deadbolts are fully inserted before turning the key. Periodically inspect for any misalignment and adjust the rubber cover as needed to ensure reliable locking.

Best regards, team Sigtuna Gear **Q: Where do you store the cable, when it's not in use?** A: Hi, thanks for your question. A velcro strap is provided with the U-lock to connect the cable to your bike frame. Please see how this is done on of the product pictures. Best regards, Team Sigtuna Gear **Q: Hi, Can I use it to lock my electric scooter?** A: Yes **Q: My mounting bracket does not fit on my frame. What do you recommend to do?** A: Hi, thanks for your question. May we ask, what kind of bike do you have? This can help us in providing a solution. Our mounting bracket is designed to fit 90-95% on all bikes, but sometimes there is case of smaller or wider tubing and in some cases triangular tubing as well. This causes the mounting bracket to not (completely) fit on the frame. With a smaller frame we recommend to use the rubbers that are provided with the lock to tighten the grip of the bracket to the frame. With a wider frame the solution is to use longer bolts to connect the bracket to the frame. The bolts that are used are common hex bolts and available at your local hardware store. With a triangular tubing we recommend to put the lock in a side-mount on the seat tube. The seat tube is almost always a regular tube that works fine with the bracket. Please let us know if this helps you connecting your mounting bracket. You can contact us at customers@sigtunagear.com.

I'm happy to have invested in such a lock. I would recommend them to anybody. The fact it has a D lock and a chain works perfectly at securing my bike to prevent theft! 10/10 ### ⭐⭐⭐⭐ Amazing lock, Great Price, Poor Bracket *by D***L on 21 February 2018* Bought one of these lock's for my road bike. I wanted something big and secure looking. On time I recieved the lock, with a strong cable that can be attached to your bike and also help secure the wheels with three keys. My only downside was the bracket that held the lock. While it's screws on very tight it has snapped twice while going down a kerb. Initially I thought it was a manufacturer defect so with the 100% guarantee Sigtuna provides I was sent a replacement with 1pm Special delivery. Unfortunately the bracket on that broke too so Sigtuna refunded me what I paid. I definitely would recommend the lock, I will absolutely keep using it as it does seem super secure and heavy duty but will carry it in a bag. I will certainly look to use more Sigtuna gear after the customer service I recieved. Unlike others I wasn't asked to provide a review for an incentive I just appriciate a good product and feel like everyone should know what a great company Sigtuna is, what a great lock this is but also that the bracket sucks. ## Frequently Bought Together - Bike U Lock - Sigtuna Bike Lock Heavy Duty Anti-Theft with 4ft/1.2m Cable, Bicycle U Lock with Sturdy Mounting Bracket for Mountain Bikes, Ebikes, Scooters - Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black - Lamicall Bike Phone Holder, Motorcycle Mount - Motorcycle Phone Holder, Handlebar Cell Phone Clamp, Scooter Phone Clip for iPhone 16 Pro Max/Plus, 15 Pro Max, S10, S20, More 4.7" to 6.8" Smartphones --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/47930542-yellow-bike-u-lock](https://www.desertcart.be/products/47930542-yellow-bike-u-lock) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-15*
