houjin1006 / light pump-bike


A bicycle pump is a necessary part of itself but has a low frequency.
Therefore I designed a pump combined with a light function mostly working as a pump but when it needed, working as a light.

And I also designed it eco-friendly and economical object with no need of extra battery by kinetic energy.
