Since drinking to excess has the ability to impair one's ability to operate any kind of vehicle, the Alcoho-Lock was developed to prevent drinking and riding.
The smart device by KOOWHO makes use of Bluetooth technology and syncs to an accompanying app. To use after drinking, the bike lock has a user breathe into the breathalyzer lock and wait for the assessment from the app. Even if a user is drunk beyond the point of being able to safely get home, the app will unlock the bike, but warns that a user should walk their bike home rather than ride it.
As an added precaution, the smart bike lock also has the ability to send an alert to a pre-registered person, so that they will be automatically notified if a biker has had a few too many drinks, making it easy to arrange a pickup for a drunken friend or loved one.
