Ever gotten into situations where you wished you had your big and bulky all-purpose pump to pump your bike? Tried using one of those portable bicycle pumps that just don't pump your bike? That's because they lack a central pin to push the air-flow stopper in your tires so that you can pump air.
I'm going to teach you guys how to make a simple and easy mobile pump for relatively cheap.
Easily the simplest DIY project you'll ever get - pun intended. You can finish this in 30 minutes or less.
1) An old all-purpose pump that has problems. You'll just need the "head" of the pump. (You can find these at bicycle repair stations or whatever local super/hyper market you have in your neighborhood.)
2) One of those cheap ball pumps. The small mobile ones. (costs about $5-10)
