In elementary school and junior high I had a Stingray 5 speed Fastback with narrow tires. In high school the film "On Any Sunday" came out. Since I was the only kid with an MX motorcycle, we modified conventional Stingrays to withstand the abuse we dished out trying to bust the moves of the great MX riders of the era: Roger de Coster, Joel Robert, and so on. We found out where the frames and handlebars broke and had our local welding shop weld in gussets and crossbars. I built up a 36 spoke rear wheel on a Sturmey-Archer 3-speed coaster brake hub with a twist grip shifter. We flew off loading ramps and stairwells chasing each other around the local college campus. This was years before lightweight BMX bicycles were offered. When I came back from university I found out my parents had sold my unique creation as well as my 1962 Schwinn Corvette klunker. I still haven't forgiven them for it.
