Your breath is the key. World'S First Breathalyzer Bike Lock
Drunk riding of bike is dangerous, the cause of injuries and accidents. Furthermore, just like drunk driving, it is against the law in Japan. However, many people are not aware about the dangers and illegality compared to drunk driving.
ALCOHO-LOCK from pro-cycle shop KOOWHO is a totally new solution consisting of a lock and exclusive application. When cyclists are about to unlock, the alcohol density level will be checked by breathing into the lock. In case alcohol is detected from cyclist’s breath, an alert is automatically sent to the pre-registered partner’s smartphone. The partner can stop their beloved cyclist from riding bike.
What is needed in order to end drunk riding of bike, it is the reform of the mindset and the power of love. To all cyclists, with love.
