If you don’t have somewhere secure to lock up your bicycle, the Hiplok ANKR Maximum Security Bicycle Anchor will provide it. When installed on a wall, the ANKR works with both chain-style and D-shaped locks. In fact, you can even use the Hiplok ANKR on the ground. Wherever you put it, it attaches with four secure wall fixings. Available in black, red, and white, this bike anchor is easy to install, but it’s not easy to break into. That’s because it has a hardened steel design and works on masonry, concrete, or wood. Additionally, the opening reaches 75 by 44 millimeters and has a rubberized spot to protect your bike frame from potential scrapes. Pair it with the Hiplok D lock, and this device will make your bicycle more secure than ever.
