Ultra-Durable SIGTUNA Bike U-Lock with 16mm Shackle and 4ft Cable

SIGTUNA, founded by a team of bike enthusiasts, is all about the ride for us! Based in Stockholm, our bicycle security systems are available in the United States, United Kingdom, France, Germany, Spain, Italy, and Japan, as we work hard to design and produce the best possible bike locks.

Regardless of your security needs, SIGTUNA will do its utmost to ensure you can go where you want, when you want. Our U-lock installation process is straightforward:

1. Choose the mounting location: Decide where on your bike you want to mount the U-lock bracket, typically the seat post, top tube, or down tube, ensuring it's easily accessible but doesn't interfere with riding.

2. Attach the bracket to the bike: Use the provided screws and a screwdriver to securely attach the bracket to the bike frame, making sure it's tightened and won't move.

3. Test the fit: Insert the U-lock into the bracket and check if it fits snugly. Adjust the bracket as necessary for a proper fit.

4. Secure the U-lock in the bracket: Once you've ensured a good fit, place the U-lock into the bracket and give it a gentle shake or tug to confirm it won't fall out during your ride.

Our bike locks come in a variety of models, including the Thor, Wodan, and Vidar, each with its own unique features:

• The Wodan and Thor models feature a high-security disc-style cylinder and a double deadbolt locking mechanism.
• The Vidar model offers special ABS shipbuilding steel, a soft-touch coating, and a silicone lock body cover.
• All models come with an easy-to-mount mounting bracket, 3 laser-cut Abloy keys, and an anti-scratch protective coating.

SIGTUNA's bike locks are designed for security and anti-theft protection, with 0.64-inch steel for high cut resistance. The vinyl coating also safeguards your bike from scratches. The interior locking size and cable dimensions are suitable for a wide range of bikes, and the waterproof and rust-proof features ensure a longer lifespan.

Each package includes a steel bike lock, a 12mm x 4ft cable for additional security, a mounting bracket, 3 keys, and 2 extra mounting screws for quick assembly. SIGTUNA stands behind its products, offering a 100% Satisfied Guarantee if you're unsatisfied with the product after the free trial.
