Hello and welcome to the forum. Do you live in Barrie, Ontario?
You will have to flesh out your request for help with your trike so we can help you build what you want. If you go to the very top of the page you will see a box with Google Custom Search.
Type in, trikes, and then click on search and you will have hours of reading to help you get an idea of just what has and can be done and then those of us who have done them or are going to do one will be more than happy to share our experiences.
Enjoy your build and post lots of photos. We love to see what your doing.
Steve.
