PumpTire: wheel concept that inflates itself

PumpTire is a prototype wheel for bike which has the grace of inflating itself. The system is simple: a tube runs along the outside of the wheel. When the bike is loaded, the tube is squeezed, which sends air into the wheel chamber. Next to the tube is a valve that regulates the desired pressure level and determines how long it should be inflated.
The creator of PumpTire is looking for financing in Kickstarter to bring his product to reality. He is asking for the not insignificant sum of US $ 250 thousand, of which he has so far US $ 8671. The closing of the investment is the October 5.
PumpTire will be available in two models: City Cruiser, for casual cyclists who only want to ride a bike for a while and tour the city, and City Pro, for dedicated cyclists who want to make good use of their bike.
