INTRODUCTION
Being a specialist of bicycle hubs,
we have been always monitoring the customer's opinions and noticed that the most important
factor that the cyclists are worried about is a flat tire. We have come to know through our
investigation that most of the cyclists ride a bike with tires of air pressure at 1.8atm
in average in spite of the required 3.0atm.
Less air pressure causes a flat tire, but leakage of the air is inevitable as long as
rubber is used inside the tire. An idea to keep pumping the air while riding a bike has
flashed into my mind and it seems better to make such a mechanism rather than waiting
for a rubber maker to produce leakageless rubbers.
After spending a lot of time, we have finally developped a hub continuously supplying with
the air while cycling. This hub is now required not only by the cyclist but also by some
other people such as wheel chair users. We will keep hearing of the customer's opinions to make a unique product that
nobody else can make.
