You wobble down the road on an old squeaky bicycle with dusty rims and spokes and its chain caked with oil. It has one of those comfortable wide seats, supported by big couch springs or bed springs. Is that where the squeak is coming from? What else, besides the rider, can squeak on a bicycle? The handlebars shaped like your uncle’s old country mustache? The rusted speedometer with the broken glass that your older brother added years ago? The brakes worn to nubs that look like old erasers? Can spokes squeak? Can they speak? Can they sing? No. But they can hum. And anyway, who knows the words?
