Scout is a bicycle alarm and finder, designed to seamlessly integrate into Apple’s FindMy network of products, allowing you to keep track of your beloved bikes whereabouts, even when you’re not riding. The lightweight, and low-profile SCOUT discretely and securely mounts to any water bottle cage using the security screws provided. Once armed (via the app or on the unit itself) any movement of a bike fitted with Scout will trigger the motion sensitive 85 db alarm alerting the owner. If a Scout fitted bike is not where the owner last left it, then they can simply locate its position using Apple’s FindMy network. The SCOUT is USB-C rechargeable and has a runtime of approximately 6 months with standard use. Riders can activate/deactivate the motion sensitive alarm, locate the device, and check the battery life, all through the Knog App. Scout is the future of bike security.
