It is wrapped with 3mm soft rubber outside, which can effectively prevent from scratching your bike paint. • The gap between the connecting plates is only 0.2mm gap. This unique design allows links to rotate smoothly around the axis, without jamming or squeaking. • This lock is only 633g, lightweight and compact. It is equipped with ETOOK special lock holder, convenient to carry while riding without any burden. • The special highlight of this new lock, is the update at the back of the holder. We adopt our designer's idea of technical anti-theft. An Apple AirTag or a Samsung SmartTag can be hidden securely in the lock holder. With the tags, the bike can be easily tracked via your smartphone.
