<meta property="og:description" content="Mr. Tuffy has nothing on Mr. Knobby, the new tire liner innovation.
It has been said that epiphany whispers to us like angels from heaven.
Other times, inspiration barks at us like junkyard dogs. When your kid
pops a flat for the umpteenth time and threatens to hijack the ipad instead
of playing outside, you scramble for a solution. So you grab your garden
shears and whatever old worn out tire you've got in the garage and make
yourself a textured tire liner. We salute you mothers, fathers and
extended family of invention.
"They Fix" is our new series highlighting other people's innovations,
workarounds and bike hacks we see here in Portland. Also, look for our
upcoming companion posts "We Fix" to see how we do bikes here at 21st
Avenue Bicycles."/>

Other times, inspiration barks at us like junkyard dogs. When your kid pops a flat for the umpteenth time and threatens to hijack the ipad instead of playing outside, you scramble for a solution. So you grab your garden shears and whatever old worn out tire you've got in the garage and make yourself a textured tire liner. We salute you mothers, fathers and extended family of invention. </p><p>"They Fix" is our new series highlighting other people's innovations, workarounds and bike hacks we see here in Portland. Also, look for our upcoming companion posts "We Fix" to see how we do bikes here at 21st Avenue Bicycles.</p></div></div></div></div></div>
