PUYL – awesome bicycle pump and bike lamp combo


The PUYL bicycle pump and LED bike lamp combination is a very clever idea indeed. The super great thing about it is actually the fact that it doesn’t need batteries, the power comes from all that pumping, which creates electricity. This product really needs to go into production. Soon.


  It is the first permanent illuminating bicycle light which does not need a battery. This combination provides an unlimited light source and a bicycle pump for urban cyclists. The idea is based on Faraday’s law of induction. Instead of batteries, it uses electromagnetic induction. The electricity is generated by moving the compressor/ magnet through the two copper coils that are located around the inner compression tube. The light’s battery is charged while pumping. The generated energy is stored in a rechargeable battery/ super cap.
