Using the Oxford Bottle Boss Tag Mount is easy. First, find the pre - existing cage points on your bike. Then, use the provided Torx security tool to screw the mount into these points. Place the mount between the bike frame and the bottle cage. Make sure it fits well as it's designed for 61 - 65mm bottle cage mount fixing positions. Once the mount is in place, insert your Apple® AirTag™ (not included). Now you can track your bike on your iPhone or iPad. As for maintenance, since it's tested to IPX7 waterproofing standard, it can handle some water exposure. But don't submerge it for a long time. Keep the mount clean by wiping it with a dry cloth regularly. When not in use, store it in a dry place. Also, check the Torx security bolts from time to time to ensure they're tight.
