Red Alert / Tire valve

Red Alert

It is very difficult to directly observe if the bicycle tire is full of air. In response to this problem, we have designed the tire pressure indicating valve for the bicycle. The valve is furnished with a pressure detection device and an indicator light. The user can directly observe the air pressure condition inside the bicycle so as to remind the owner to pump up it in time. And, he may know that the tire is full of air or not while pumping up.
