Knog Scout Bike Alarm & Finder
A bike alarm that fits under a bottle cage and doubles as an Apple Find My tracker for iPhone users. Moving the bike sets off an 85 dB alarm; Knog quotes up to six months per USB-C charge (about two if armed daily). It is rated IP66 and weighs 25 g.
Uses Apple’s Find My network, so you need an iPhone or iPad to set it up — it can’t be added to an Android phone.
