Ever since John Dunlop invented the pneumatic tire for his son’s tricycle in 1887, tinkerers have crafted various self inflating bicycle tires using either a pump built into the hub or using the compression between tire and road as the pump. San Francisco entrepeneur Benjamin Krempel wants to commercialize this potentially useful idea, calling his product PumpTire and utilizing Kickstarter to crowdfund this endeavor.
Krempel’s PumpTire seems to have merit, but the coolest part of his Kickstarter video is mounting a small video camera in the hub to demonstrate how well the inflator works.

i wonder how it wears…
…he patterned it after my self-inflating ego…obviously…
