Our team works tirelessly to design and manufacture the most robust and user-friendly bike locks, catering to all levels of security needs. Whether you require a simple U-lock or a more comprehensive locking system, we've got you covered. Our products, including the Thor, Wodan, and Vidar models, are crafted from high-quality materials and feature innovative locking mechanisms to deter even the most determined thieves.

Installing our U-lock is a straightforward process that anyone can master. First, choose the ideal mounting location on your bike, such as the seat post, top tube, or down tube, ensuring it is easily accessible but doesn't interfere with your riding. Next, use the provided screws and a screwdriver to securely attach the bracket to the bike frame. Test the fit of the U-lock in the bracket, making any necessary adjustments to ensure a snug hold. Finally, place the U-lock into the bracket and give it a gentle shake or tug to confirm it won't come loose while you're on the move.

Our bike locks come with an array of valuable features, including easy-to-mount mounting brackets, 3 laser-cut Abloy keys, and an anti-scratch protective coating to maintain the lock's pristine appearance. Additionally, our high-security disc-style cylinders and double deadbolt locking mechanisms provide unparalleled protection against theft, while the smooth keyhole covers and soft-touch coatings add a touch of refined elegance to your bike's aesthetic.

Whether you're a daily commuter, a weekend cyclist, or an avid mountain biker, SIGTUNA has the perfect security solution to safeguard your two-wheeled companion. Our durable steel construction, versatile designs, and user-friendly features make our bike locks the go-to choice for discerning riders who demand the utmost in security and convenience.
