These were manufactured by American Steel and Aluminum in Los Angeles, California. They were marketed through JC Penney department stores in the U.S. The frame was aluminum and the fenders were stainless steel. The rear brake was operated by a lever on the handlebars with a cable going to the rear. Power was supplied by a small engine. This unit is very original down to its seat with El Tigre emblazed on the rear. One seam has had an amateur repair.
