Re: Super psyco found his fun =D
Welcome to the forum!
If you want to go that fast, I would first concern myself with building a bike that can safely handle that kind of speed. Bicycles were designed to merrily cruise at 10 to 15 mph, with a few high speed downhills now and then. Doing it with a typical bike is like asking a Toyota Yaris to cruise at 180mph. Not gonna happen where you will live to tell the story.
There are all kinds of high speed modding threads at this site. Just surf around and keep bookmarking the intresting threads.
Very few have made it into the 50 mph club.
