BTPS system which real-time understand the pressure of the tire of the bicycle via iPhone etc.

Failure to manage the air pressure of the tire may cause puncture, but it is very troublesome to set up measuring instruments one by one. Therefore, by constantly setting a small sensor in the tire, an item that made it possible to manage air pressure in real time has been entered in kickstarter. Once you set it, it is a handy item that you can always know the air pressure with a device such as iPhone.

When measuring the air pressure of the tire, it is necessary to set such a measuring instrument on the tire, which takes time and effort. Although there is a danger that the tire air pressure drop leads to puncture, this is not something that can be measured frequently.


Therefore, we developed a compact measuring instrument equipped with a sensor to measure air pressure and are developing a system that allows you to easily see pneumatic pressure simply by setting it on the tire at all times. This BTPS seems to be the world's first bicycle (electric bicycle) to measure air pressure.


The board looks something like this. I can understand it compared with hands, but it is a very small size.


Battery is about the size of a button battery.


This is set between the wheel and the tire.


Measurement results can be output to iPhone and other devices. Of course, data transmission is done wirelessly.


The air pressure of Rear (rear wheel) changes as air is introduced.


Such a system has already been installed in automobiles, but it has not been a bicycle before.


With this you can know the air pressure of the tires in motion in real time.


If the air pressure of the tire deviates from the proper value, there is also a function to inform you with an alarm like this. With this function, for example, damage to the sidewall caused by the decrease in the air pressure of the tire,Snake bite punkIt is also possible to prevent.


In addition, the tire pressure is also related to fuel consumption, and if it is outside the proper value, the fuel consumption will be worse. If this system is introduced, since it warns that proper air pressure of the tire will be released, air pressure management of the tire becomes easy and the number of times the expensive lithium ion battery loaded on the electric bicycle can be charged can be reduced It also leads to improved fuel economy.


Battery life is 2 years, air pressure can be measured from 0 to 12 bar (174 psi), communication standard is ANT + & Bluetooth compliant, weight is about 7 grams.


Measurement results can be output to iPhone, smartphone, watch, bicycle equipment.


And it is meant to be used not only for tubeless type tires but also for tubular type tires.


It is to withstand hard use such as downhill, and even to be able to use it for motorcycle, usability is likely to be quite good.

Currently we are recruiting funds on kickstarter and you can earn one set if you invest 140 dollars (about 12,300 yen), but you need to pay another 20 dollars (about 1800 yen) as a shipping fee There is. The deadline is 6:00 pm on January 28 (Monday) in Japan time. In order to be in time for the motorcycle season of 2013, I would like to be able to ship in May.
