Based in Stockholm, our bicycle security systems are available globally, including in the United States, United Kingdom, France, Germany, Spain, Italy, and Japan. We work diligently to design and produce the best possible bike locks to ensure our customers can go where they want, when they want, with the level of security they need.

Our product lineup includes the Model Thor, Model Wodan, and Model Vidar. Regardless of your security requirements, SIGTUNA has a solution to safeguard your bicycle.

To install our U-lock, follow these easy steps: 1. Choose the mounting location: Decide where on your bike you want to attach the U-lock bracket, typically the seat post, top tube, or down tube. Select a spot that is easily accessible but doesn't interfere with your riding. 2. Attach the bracket to the bike: Use the provided screws and a screwdriver to securely fasten the bracket to the bike frame, ensuring it doesn't move or slide around while you ride. 3. Test the fit: Insert the U-lock into the bracket and check that it fits snugly. If the fit is too loose or tight, adjust the bracket as necessary. 4. Secure the U-lock in the bracket: Once you've confirmed a proper fit, place the U-lock into the bracket and give it a gentle shake or tug to verify it won't fall out during your ride.

Our U-lock options include the Orange Bike U Lock, Yellow Bike U Lock, Grey Bike U Lock, Yellow Folding Lock, Black Folding Lock, and Black Long U Lock. Each lock features an easy-to-mount mounting bracket, 3 laser-cut Abloy keys, and an anti-scratch protective coating.

The locks also offer additional security features, such as a high-security disc-style cylinder, double deadbolt locking mechanism, smooth keyhole cover, special ABS shipbuilding steel, soft-touch coating, and silicone lock body cover. These features provide heavy-duty protection against theft, ensuring your bicycle remains safe and secure.

The U-locks come in a variety of sizes to accommodate different bike models, including mountain bikes, e-bikes, and scooters. The lock dimensions range from 7.5 x 2.25 x 1.5 inches (folded) to 13.4 x 7.7 inches, with shackle diameters from 0.315 to 0.63 inches.

Our customers have consistently given our bike locks high ratings, with an average of 4.5 out of 5 stars across over 11,000 reviews. This feedback reflects our commitment to providing reliable, durable, and user-friendly bicycle security solutions.
