I though the older model big red was the 200e? Maybe, you better start by making sure of what you have since you may be buying parts and don't want to spend money on the wrong stuff. Welcome to the site. I have a buddy up in Hollywood Fl near the circle. He has picked me up several nice trikes from down your way. There was a huge atc shop in miami at one time and they even sponsored thier own racing team. I'm sure there are some really trick old trikes sitting in a couple garages and sheds down there. Keep you eyes open in the local trade papers for some cool stuff. And welcome to the boards. Best of luck with your trike.
