This photo just shows the way I did my back seat. Again, my way. You may want something all together different. Thats the fun part about building your own Trike. Its just like Burger King. (YOU CAN HAVE IT YOUR WAY) The handle bars you see in these photos are just 3/4" conduit that I made just to get an idea of what I will need for bars to reach back where I need them. As things progressed, I found that fining bars that were long enough became a big challenge. Later you will see how I overcame the problem. Often when you build your own project, you find that you have to get a little creative to make things work. One thing I knew that I wanted in my Trike was storage. You can never have to much storage. I built in arm rest in the back seat that left up for small storage areas on both sides. These have been very handy places for small items that need to be handy. My next Trike will have less seat area and larger storage. I also built storage under the rear seat. My battery box also is under the rear seat.
