Hello MinibikeAZ, Your minibike is an 1100 series Fox Sprite. The license plate / tail light bracket that is welded onto the rear of the frame means it was made somewhere between 1965 and 1969. The two bolts hanging down underneath the seat were to attach a metal tray that held a 6 volt battery to operate the headlight and the tail light. The sprite did not have a brake light. The model 1160 was a pre-welded kit. It came in pieces which you assembled yourself and used whatever motor you wanted and cost $59.50. The model 1104 came pre-assembled and again you used whatever motor you wished and cost $74.50. The model 1143 came fully assembled with a 2 1/4 hp Lauson four cycle motor and cost $124.50. The lighting kit was an option you could add for an additional $14.95. The wheelie bar assembly is not original and was added by one of the previous owners. Hope this helps. If you have any more questions...give me a shout. Ogy
