There really are no records to know how Jockey Cycles many were manufactured but several web sites estimated about 100. The cycles were sold across the country before the company went out of business.
The cycle in the picture below was purchased by my wife's grandfather around 1950 and has been in her family all these years. She rode it, our children rode it, and now the grandchildren are riding it. This instructable gives information about the reconditioning of our Jockey Cycle.
