Bicycle theft is very common, which is why the company TECH 4 PEOPLE SRL has created a system that allows you to conceal an Apple Airtag within the frame of the water bottle holder. The total length of the connector is 77 mm, the Airtag is placed inside and then the rubber cap is fitted, while the bottle holder is added on top of this system. Essentially, the system acts as a rubber layer between the bottle holder and the bicycle frame. It does not attract attention and is not visible. The product is made from rubber silicone, offering increased durability and a long lifespan.
